Bitcoin rulez and you can also keep your opinions on others choices with it to your self.

I'm sure a lot of you are going to be pain-stricken to hear of such events, but yesterday I chose to use a dirty old bitcoin/fiat ATM. But hold the spears before you hear me out. The greatest thing about bitcoin is no one can challenge how you spend your value when you see fit and never forget that. Also I understand if you're not a poor shmuck like I, then this post probably doesn't apply to you at all.

I've been in a rut for a long time, bitcoin and crypto helped me get partially out of that rut by seeing the potential when I got in early 2017. But let's be honest, what fun is hodling? dreaming of things you could trade coin for in the future; always believing your sats will go further in the future. It is a very likely probability given the time btw, but life is actually precious. Pouring too much of your reward of working time of society into an asset hoping some day you'll get rich, again not saying that's not likely but I am saying what's more likely is you're becoming blind to the greater investments in life. the progressions in other technological fields that you may have been excited about but had your dreams fade over time, perhaps for the same reasons that brought you to the great orange currency.

I wanted to get into a specific field of work over the summer, having 3/4 of the physical gear required but missing some critical pieces and not having the fiat as my credit is ruined, my bills keep me stretched, etc; I couldn't complete my work goal. Fast forward to the past weekend, thinking about cyber Monday and black Friday and knowing I had a chunk of coin and a bit of fiat to work with I decided to pull the f*cking trigger, just like buying bitcoin I traveled to a bitcoin atm, fully prepared to pay the fee. I planned the entire expense out to the T, and I really asked myself "is this what I want? do I see value in this?" and I remembered the Rick and Morty meme with the bitcoins, where retard Rick is saying "hey if you see value in this, and no one else does, who cares". Even if 99% of you guys don't see value in what I've chosen to do, I don't care, because I do and even in time if the value of what I've traded my coin for falls. Perhaps I've used that equipment to make twice as much coin as most of you could hope to achieve threw simply hodling what you have. Perhaps I'll be wrong but also perhaps bitcoin will be in a quagmire for the next 2 years and I have lots of time to recoup any trade losses anyways while everyone greedily hodls and waits for something called a moon lambo---- IT'S CALLED THE TESLA CYBER TRUCK BY THE WAY.

All I'm trying to get at is bitcoin is YOUR freedom for YOUR choices, no person or bank, relative or friend should discourage you from using it as you see fit, which is exactly what satoshi designed it for. If you want to spend your bitcoin, do it if you can justify the trade in value- it was a hard choice to part with coin for this hardware but I see the value it can bring me in the future and to me, that's all that counts because in the last 24 hours my attitude is up more then bitcoin has been in the last 2 years because of my choice.

I want to mention though, anything I've ever bought by trading coin for fiat or directly, I treasure and take great care of. The first thing I ever bought with bitcoin was an umbrella which I used tonight to keep me dry and not cranky, it's just next to me as I type. Do what you see fit with your sats, if it keeps your feet dry when you're between pay then it sounds worth it to me, because those sats can always be bought back if you keep working hard because you're still in good health.

Live long, love bitcoin, use bitcoin and improve your lives!

Lost Bitcoin (Maybe Stolen?)

So I use the edge wallet on my iphone for some time now (it used to be called Airbitz) and i had about $3k in bitcoin I've been holding for some time now (haven't been able to purchase more in about a year due to change in work). Anyways I check once maybe every month or so and I log in yesterday and I have not bitcoin wallet or bitcoin.

I message support they guide me to a restore wallet function which shows that my bitcoin was sent to some wallet on November 7th. I have no other wallet besides a coinbase account... I have no recourse as far as I can see. I have no idea what this transaction is. All my money in BTC is just gone. I have here all the info on the transaction, idk if this is useful at all:

https://www.blockchain.com/btc/address/132ba11ppQDN2krpHhu61qi3hP8cKrAQet

Does anyone have any idea what I can do or if there's any way I can figure out where it was sent or what happened? I went thru everything in all my emails and bank accounts for November 7th. I went and saw a friend preform poetry that day and I got a new camera I had received in the mail... no Bitcoin transactions happened then....

Any help is appreciated, thank you.

What happened with MATTIC should not surprise anyone — here’s why:

‘Panic?’ So theyre chalking it up to FUD as their explanation? Smh. For any of you whose been involved in the crypto game b4 Q417, you already know what I’m about to say. For all the rest: this was a 4PD if I ever saw one.

4PD (disambiguation) is one of many slang acronyms / memes that really apexed in usage circa 2016 & pretty much dissipated after cryptowinter. It stands for 4chan Pump & Dump — back when the first DEXes were launching & the only ‘stablecoin’ was USDT (which remained the only stablecoin until after BTC ATH which brought widespread, global attention to regulators) & the notion was anyone who had 10+ BTC (which wasnt inconceivable back when I started trading at $200 per coin) would scour 4chan and dark web message boards with forum posts titled “4PD LFXM” where X = 1 user or 10 BTC .

These simplistic yet complicated, paradoxical form of easily spotted & instantly recognizable code would let pump & dumpers (whales only) seek out each other so if I post 4PD LF2M then without needing to read the thread or post (of which was usually vague or left empty) I would know right off the bat that there’s a group of 3 whales who all are willing to commit 10 BTC each, thus 30 BTC total seeking 2 more ppl or 20 more BTC.

This was so rampant in 2016 (the golden year of crypto for early adopters) that anyone who had any experience trading knew right away to stay the fuck away from any coin/token with a market cap under 50 million — I must confess I am guilty of being apart of one of these groups.

We pumped golem, bcc (bitconnect) Bitcoin gold and a slew of other shitcoins that don’t even exist anymore. We would all buyin & made the whole community FOMO then dump at the top.

The only problem was finding a group you can trust ; which fortunately for SWIM worked out great as they used software to create an algorithmic system of escrow to make sure we had proof of stake and no need to trust each other.

Anyone’s curious how it worked out in terms of ROI; basically we’d(they’d) dump 10 BTC each & 50 BTC into a shitcoin and split the return at the top of the wick which usually was anywhere from 25%-10,000% profit (yes, I know...)

Technically they/we should all be in jail for what SWIM did. If it makes you feel any better, SWIM lost 80% of everything in cryptowinter and SWIM donated tens of thousands of $$ to irc unicef & st Jude.

Now? SWIM has nowhere near the net worth he had back then but is comfortable enough for me to focus on my research & startup while not needing to work for food/bills.

Disclaimer SWIM = someone who isn’t me. The story above is strictly an alleged hypothetical; unsubstantiated & without evidence of said events having occurred. SWIM is not liable for any incidents of pump and dumping nor does SWIM know anybody that is. Additionally described above is nothing more than pure conjecture and a potential hypothetical for educational and entertainment purposes.

Einstein dies and goes to heaven. First person he see he asks, “Excuse me? What’s your IQ?”

The person replies, “280”.

Einstein says, “Great! We can talk about astro physics!”

Second person he runs into, he asks the same question, “What’s your IQ?”

The person replies, “150.”

“Great!” says Einstein, “We can talk about events of the day!”

Third person he sees, he once again asks about their IQ.

This time the person says, “45!”

Einstein says, “Great! Where do you think the Bitcoin market is headed??!!”

Beginner's Guide to Trading Crypto. Part 11

Money Loves Security And So Do Cryptos: A Brief Guide Down Crypto Wallet Lane

Since time immemorial people have been keeping their money and valuables in safe places. Be they purses, clay pots full of coins buried in their backyards or treasure chests hidden in caves with piles of bones strewn around to keep unwanted visitors at bay, they means conceived for safekeeping hoarded valuables are just as creative as they are limitless.

The advent of cryptocurrencies as a new class of valuables and assets instantly spawned the need to keep them safe from the clammy hands of criminals. The logical solution was to develop wallets that would be used to keep cryptos safe. As a result, a multitude of wallets have emerged offering all kinds of added services to their users while remaining means of storage at heart.

There is a huge variety of wallets available: Coinomi, GreenAddress, Blockchain.info, Atomic, Exodus, Jaxx, Electrum, Copay, Bread, Airbitz, Armory, Mycelium, Blockchain Wallet and dozens of others, each offering their services to suit any taste.

https://preview.redd.it/tai1ax5q3u341.jpg?width=1200&format=pjpg&auto=webp&s=0a33622327c7e52eea02e77f7c843423e6aeba12

Types Of Wallets

There are several types of wallets available to users and everyone must decide for themselves which one suits their needs best.

Hardware wallets: These are the most secure and reliable wallets available, since they are not connected to the internet at all. Hardware wallets are like flash memory cards that store the user’s cryptocurrencies and access offline. A bright example is the Trezor wallet, which is deemed to be impermeable to hackers. Unless the user loses the device itself, it is safe to assume that the cryptos will stay on it indefinitely and no one will ever gain access to them.

Online, Web or Hot wallets: These are online services, or online wallets that offer to store the user’s cryptos online with direct access to the internet at any time. In essence, online wallets are online accounts in which users store their funds. The risks are very high, since exchange wallets are routinely being hacked and the cryptos stored therein stolen.

Desktop wallets: Desktop wallets are software programs that can be downloaded and installed on a PC and will only be accessible from the device they were downloaded onto. The risks are the same as with hot wallets and another added inconvenience is that loss of the device or loss of access to it means loss of all cryptos stored on it.

Mobile wallets: Mobile wallets are software programs that can be downloaded onto a mobile device, such as a phone or a tablet. There are wallets for Android and iPhones and all of them bear even greater risks than hot wallets. Since mobile devices are susceptible to theft and a variety of viruses, it is extremely risky to store cryptos on them. Though access to the cryptos without private keys is impossible, unless the user stores them on the device, loss of all cryptos with the mobile device is guaranteed.

Paper wallets: Paper wallets are offline cold storage for cryptocurrencies. This is by far the safest means of storing cryptos, which includes printing the public and private keys on a piece of paper and storing it in a safe place. The keys are printed in the form of QR codes for convenience. With paper wallets, the user has complete control over their funds and the only risk lies in losing the piece of paper with the keys.

Other types of wallets: Apart from the five main types of wallets, there were attempts at creating other types of services, such as atomic wallets using atomic swap technology and even combinations of mobile/hot/cold wallets. Despite limited success, hybrids models of wallets did not become popular.

Main Pros And Cons

When looking at wallets and their main advantages and disadvantages, it is easiest to speak of the division between cold and hot wallets.

When speaking of cold wallets, such as the Trezor Bitcoin wallet and Ledger Nano S or X, the same issue will be observed, and that is the fact that such wallets can be physically lost. Though anyone who ever finds them will never be able to gain access to the stored cryptos without the private keys (unless they are pasted on the device), loss of all cryptos on the device is guaranteed. In addition, cold wallets can be difficult to install and are inconvenient for frequent use.

https://preview.redd.it/ff2dukdx3u341.png?width=1021&format=png&auto=webp&s=f36cdc26b13f33433c5124f5e5a67c0e40f9dbf4

Hot wallets are far more susceptible to risk than their cold counterparts. Though hot storage is much faster and convenient with a wide variety of options from Coinbase to Blockchain.info, the risk of cybercrime runs high. Mobile or desktop storage is also considered to be hot storage and is also risky, if the device is damaged or destroyed.

Bitcoin Problems

Bitcoin, as the firstborn cryptocurrency, was born with a number of defects. One of the main problems of the king of cryptos is the yet unsolved scalability problem. This refers to the limit on the amount of transactions the Bitcoin network can process due to the limited size of and frequency of blocks in the Bitcoin blockchain.

Said problem poses some difficulties to all Bitcoin users and leads to what is known as backlog in the blockchain. The backlog leads to long queues of transactions in the system. With the average transaction time in the Bitcoin blockchain being around 7 transactions per second and the theoretical maximum standing at 27, it is not difficult to understand how long users of the blockchain have to wait for their transactions to pass in times of heightened demand – the time is in the hours and sometimes even days.

Bitcoin Wallets Review

Since Bitcoin is the most popular cryptocurrency on the market, it is logical to judge wallets by their support of the first cryptocurrency. As such, the following will be a brief review of some of the best and most popular Bitcoin wallets on the market.

Online Bitcoin Wallets

Online or web wallets are the most popular ones out there and the best Bitcoin wallet overall is widely considered to be Blockchain.info, which is easily accessible and convenient for everyday use with good security. As an anonymous Bitcoin wallet, Coinbase follows in the lead with its ability to store a multitude of various coins, but with the same security risks that are inherent to all hot wallets.

Android Bitcoin Wallets

Android is the most popular mobile system in the world and plays host to a number of good mobile wallets. The best Android Bitcoin wallet is widely considered to be the Electrum Bitcoin wallet with its excellent reputation, good security and convenience. Though Electrum has some occasional glitches, they are never critical. Another excellent wallet for Android is the Coinomi wallet with its support for a wide variety of cryptos and excellent user support, which even allows for restore options using special phrases. Coinomi has its issues as well, such as occasional exchange glitches, but the many pros outweigh the cons.

Bitcoin Hardware Wallets

The undisputed leaders as the best hardware wallets for Bitcoin are Ledger Nano X and S, Trezor T and Trezor One, and Keepkey. Bitcoin hardware wallets are comparable in their security, accessibility and usability. The difference is mainly in the price, which ranges from $165 for Trzeor T to $59 for the Ledger Nano S model. In fact, the Ledger Bitcoin wallet is often called the king of hardware wallets. The KeepKey Bitcoin wallet is the in the top three hardware wallets as a convenient and stylish device. Though KeepKey supports over 40 assets, it still lacks coin support.

Bitcoin Wallets For iPhone

iPhone’s iOS system is the second most popular for mobile devices in the world and has support for some good wallets as well. The best iOS Bitcoin wallet for iPhone is considered to be the Abra software, which offers credit card support for topping up crypto balances and a good user interface, which is even more oriented at exchanges. The next software is Edge, formerly known as Airbitz. The Edge wallet is best known for high security and good user-friendliness along with multi-currency support.

Bitcoin Wallets For Windows

Bitcoin wallets for PC are very popular and Windows is leading the way with some excellent offers for wallets. Atomic is by far the most advanced and the best option for Windows users as it offers Atomic swaps technology as its basis. The application offers a wide variety of operations and supports over 300 cryptocurrencies. Exodus is the second most popular choice as a desktop only wallet with support for Bitcoin and many other altcoins. Exodus offers its users a good interface and it is free for use.

Bitcoin Wallets For Mac

Since Atomic and Exodus are cross-platform wallets, they can be used on Windows and Mac. Apart from them, there are also Jaxx and Electrum, which can be used on Mac. Jaxx is a multi-currency wallet with support for around 40 cryptos and has a PIN feature. In addition, Jaxx is free for use. Electrum is one of the oldest desktop wallets and is a lightweight wallet that does not require the full blockchain to operate, meaning less storage needed for its operation. The wallet requires a PIN and is essentially a desktop bank with good security and usability. Electrum is also a Bitcoin wallet for iPad, since it can be used on mobile platforms.

Bitcoin Paper Wallet

Since storing cryptos online on exchange or hot wallets or even on devices is risky, it is oftentimes more convenient to use a simple printer to print out the keys and store them. BitAddress offers a convenient and easy to use, step by step guide to creating a paper wallet with the added benefit of sleeping in peace, known that nothing and no one will ever threaten your Bitcoins.

https://preview.redd.it/bh7wi0d64u341.png?width=600&format=png&auto=webp&s=9f7fbd269eea43ac3b8897ad470553ba8b3c730d

Checklist

When embarking on the journey of creating your first wallet, think well of which type to use. The type will depend on the priorities that stand before the user. If security is paramount, then paper or cold storage wallets are the go-to solution. If frequency of use is the name of the day, then hot wallets and their inherent risks are the best way to go.

The most frequent questions related to wallets are how to add money to a Bitcoin wallet and how to set up a Bitcoin wallet. Both questions have no single answer, as each wallet offers its own instructions on how to top up balances and how to set them up. Therefore it is recommended to study all instructions carefully prior to operation.

Either way, there is no silver bullet and some features will have to be sacrificed in deciding how to store cryptocurrencies. The one thing that is constant is the need to store Bitcoins and cryptos and make use of them.

Anthony Pompliano predicted Bitcoin to reach the $100,000 rate by December 2021

Morgan Creek Digital co-founder Anthony Pompliano stated in one of his interviews that the upcoming halving of bitcoin in May 2020 would be a significant event for the main cryptocurrency so that it will increase its price many times over.

https://preview.redd.it/i2pbysbeet341.png?width=1000&format=png&auto=webp&s=653777827700c128f4e8cbd2b6e4ac885d782a94

He noted that the growth of Bitcoin would be gradual.

According to Pompliano, Bitcoin entered a two-year growth phase. However, the cryptocurrency’s volatility in this period can reach up to 30%.
