Quite tricky...

Bulls Stamped Toward $12K Bitcoin Price as Weekly Close Approaches

Bitcoin price is making a strong push toward $12,000 with just 24-hours before the weekly close occurs

Despite multiple rejections at the $12K mark, #BTC continues to make higher lows and traders are buying dips at underlying support levels

Chainlink reached a new all-time high at $19.80 and Ether is struggling to push above $430

Typically, for Bitcoin (BTC), weekends are marked by reduced trading volume as day traders take a break and the CME Bitcoin markets are closed.

Experienced traders will also know that exchange order books thin out during the weekend, providing opportune moments for clever Bitcoin whales to exploit these gaps and sway the price through whipsaw volatility.

This Saturday things are different as the scenarios mentioned above are not deterring traders from a renewed push to the $12K mark.

If the current move to the key level fails, it would be the second time in a week and for some analysts multiple rejections at a key resistance level can be a bearish signal.

On the other hand, there are also an equal number of traders who will argue that multiple retests of a key resistance level heighten the chance that it will be breached on future attempts.

A few positives for Bitcoin price are: the daily chart continues to show a pattern of higher lows, the RSI is in bullish territory at 66, and traders show strong interest in buying into each dip, as shown by the rising purchasing volume on the daily timeframe.

In the event that traders can manage a 4-hour close above $12,000, Bitcoin will need to pursue a daily higher high above $12,068 and $12,123 then things will get quite interesting.

For the time being, we can see that the price is simply compressing into a tighter range within the pennant and drop the lower trendline should be supported by the high volume VPVR node extending from $11,730 to $11,500.

Typically a drop from such a pennant would warrant some concern but given buyer’s demonstrated interest in buying since July 28th and further back to March 12, it seems bulls will eventually have their way by flipping $12K to support in the short-term.

As Bitcoin fought to retake the $12K level, the performance from altcoins has been a bit of a mixed bag.

Chainlink (LINK) continues to lead the market, rallying 12% to reach a new all-time high at $19.80. #Ether (ETH) appears to be losing steam as it pulled back 2.2% and struggles to reclaim the $340 level.

Meanwhile, EOS finally managed to break above a key resistance to rally more than 18% and currently trades for $3.75

According to CoinMarketCap, the overall #cryptocurrency market cap now stands at $373.4 billion and Bitcoin’s dominance index is currently at 58.8%.


Switzerland is good for business development as it is located in the center of Europe

Switzerland is good for business development as it is located in the center of Europe. It is convenient to get there for meetings with European partners. A prestigious jurisdiction is especially important for crypto companies that work with customers' money.

Today we will talk about Crypto Valley. What is it and why will Simba be based there?

We have already spoken about the fact that in 2016 the authorities of the city of Zug launched an experiment: they offered residents the option to pay for utilities and government services with bitcoins. Then, Swiss Railways allowed passengers to exchange cash for cryptocurrency in ticket machines. Local officials are satisfied with the pilot project and continue to introduce blockchain into the daily life of residents. There are over a hundred fintech startups operating in Zug now. According to PwC, every 11th fintech startup on the planet opens in Zug.

Due to the cluster of decentralized startups, the canton has been nicknamed Crypto Valley (http://gdi.ch/media/cryptovalleymap_impuls_v2.pdf). The following are located there: the headquarters of the Ethereum blockchain platform; the Monetas cryptocurrency payment system; Bancor, the platform for creating new cryptocurrencies; Bitcoin Suisse AG, the Bitcoin ATM network operator; the Xapo bitcoin wallet provider; the ShapeShift cryptocurrency exchange; and the Lisk blockchain platform, which is competing with Ethereum.

The Crypto Valley Association has (https://cryptovalley.swiss/) recently been established in Crypto Valley. It is engaged in the development of an ecosystem for decentralized technologies, prepares proposals for regulators, launches research projects and organizes events. The association brings together large companies (Luxoft, UBS, PwC, ConsenSys, Monetas and Thomson Reuters), investors, the Zug government, the University of Lucerne, and blockchain startups.

On the map below, you can see where the Swiss company Simba will be registered: 130 meters from #Ethereum #Foundation near #Tezos #Foundation and #Bitcoin #Suisse

Lion Simba chooses only the best locations for itself!

hodlmon.sh: a UTXO monitoring methodology and script for true connoisseurs of security, paranoia and BTC maximalism

Submitting this to help strengthen the community, and for review:

hodlmon.sh: a UTXO monitoring methodology and script for true connoisseurs of security, paranoia and BTC maximalism

Monitor canary UTXOs for early detection of compromised private keys BEFORE funds are lost, using your own full node for maximum privacy and trustlessness. Note that you will need to implement your own notification strategy (email, push, sms, etc). This script is intended to run on your full node, but can be run from any machine with RPC access to your full node.

hodlmon.sh is designed to check if a given UTXO (i.e. a specific output of a specific btc transaction) has been spent or not. This can be used for early and proactive detection if a seed phrase or private key has been compromised, so you have time to move your btc before full compromise happens.  In order for this to work, a small amount of btc should be sent to an address controlled only by a given seedphrase, with that seedphrase being part of a multisig wallet or a seedphrase+passphrase wallet, and the majority of your funds controlled in the seedphrase+passphrase or multisig wallet. The idea is to leave the small amount of btc (the canary utxo) in the address, so that it never moves unless the seedphrase that controls it has been compromised and all funds in the wallet swept. In this way, you use those compromised sats to buy information about the current security status of your wallet(s).

Example usage:
Set up a cron job to run hodlmon.sh every 30 min to check if transaction output at index "0" for transaction with id "123" has been spent already. Use "my_utxo_nickname" as a friendly name for the UTXO (to differentiate between multiple wallets)

*/30 * * * * /path/to/hodlmon.sh 123 0 my_utxo_nickname > /tmp/hodlmon_log 2> /tmp/hodlmon_err_log

Usage scenario #1: Seedphrase (A) + passphrase (A')
Majority of funds are held in a wallet controlled by both the seedphrase and passphrase, A and A'. A token amount of btc is controlled only by seedphrase A.

A + A': majority of funds
A: canary UTXO

hodlmon.sh is used to monitor the canary funds locked by A, so that if it is discovered that A has been compromised, the funds locked by A and A' can be moved to a new wallet before the passphrase A' can be cracked and all your funds exfiltrated.

Usage scenario #2: multisig e.g. 2 of 3, with seed phrases A, B and C
Majority of funds held in a multisig wallet controlled by 3 seedphrases A, B, and C.  3 small canary UTXOs are held in wallets each controlled by A, B or C, respectively.

A + B + C: majority of funds
A: canary UTXO 1
B: canary UTXO 2
C: canary UTXO 3

One benefit of multisig (e.g. 2 of 3) is that even if 1 key is compromised, your funds are safe, since at least 2 keys are needed to release funds. But how do you that none of the keys has yet been compromised? If you create separate wallets controlled each by only 1 of the individual keys, and use hodlmon.sh to monitor whether those UTXOs have been exfiltrated, then you can detect partial compromise of your setup before a full exfiltration event takes place, so you can move your funds to a new multisig wallet with freshly generated and uncompromised keys.

Example of 3 cronjobs to monitor all 3 canary UTXOs:
*/30 * * * * /path/to/hodlmon.sh 123 0 key1 > /tmp/hodlmon_log_1 2> /tmp/hodlmon_err_log_1
*/30 * * * * /path/to/hodlmon.sh 456 0 key2 > /tmp/hodlmon_log_2 2> /tmp/hodlmon_err_log_2
*/30 * * * * /path/to/hodlmon.sh 789 0 key3 > /tmp/hodlmon_log_3 2> /tmp/hodlmon_err_log_3

How long does it take for my balance to unlock?

Your balance is unlocked after 10 confirmations (which means 10 mined blocks). A block is mined approximately every two minutes on the Monero network, so that would be around 20 minutes.

How can I prove that I sent a payment?

The fastest and most direct way is by using the ExploreMonero blockchain explorer. You will need to recover the transaction key from your wallet (complete guide for GUI / CLI).

How do I buy Monero (XMR) with Bitcoin (BTC)?

There are dozens of exchanges that trade Monero against Bitcoin and other cryptocurrencies. Check out the list on CoinMarketCap and choose the option that suits you best.

How do I buy Monero (XMR) with fiat?

  • Kraken (USD and EUR): old-school, decent exchange. They might require your documents for verification and approval of your account.
  • LocalMonero: peer-to-peer exchange. They have pretty much everything as a payment method and they support hundreds of fiat options.

How can I quickly exchange my Monero (XMR) for Bitcoin (BTC)?

There are multiple ways to exchange your Monero for Bitcoin, but first of all, I'd like to remind you that if you really want to do your part for Monero, one of the simplest ways is to get in touch with your merchant/service provider and request for it to accept Monero directly as payment. Ask the service provider to visit the official website and our communication channels if he or she needs help with system integration.

That being said, the community has been recommending two services in particular, XMR.TO and MorphToken. These services are only recommendations and are operated by entities outside the control of the Monero Project. Be diligent.

How do I mine Monero? And other mining questions.

The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit r/MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.


2. Wallet: CLI & GUI

Why I can't see my balance? Where is my XMR?

Before any action there are two things to check:

  1. Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
  2. Is your wallet fully synchronized? If it isn't, wait the sync to complete.

Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized.

You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait.

If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.

How do I upgrade my wallet to the newest version?

This question is beautifully answered on StackExchange.

Why does it take so long to sync the wallet [for the first time]?

You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization.

Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).

I don't want to download the blockchain, how can I skip that?

The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld.

Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy. A remote node can't see your balance and it can't spend your XMR.

How do I restore my wallet from the mnemonic seed or from the keys?

To restore your wallet with the 25 word mnemonic seed, please see this guide.

To restore your wallet with your keys, please see this guide.


3. Wallet: Ledger

How do I generate a Ledger Monero Wallet with the GUI or CLI?

This question is beautifully answered on StackExchange. Check this page for the GUI instructions, and this page for the CLI instructions.


4. Nodes

How can my local node become a public remote node?

If you want to support other Monero users by making your node public, you can follow the instructions on MoneroWorld, under the section "How To Include Your Node On Moneroworld".

How can I connect my node via Tor?

This question is beautifully answered on StackExchange.
