EDIT 2: As usual this thread is being heavily downvote-brigaded, most likely by the Monero community whose privacy I call out for being exposed as ineffective, especially next to Dash's solid 5-year track record of proven effective privacy with PrivateSend
TL;DR As other community thoughtleaders like Jonald_Fyookball, Roger Ver, BCH devs et. al and those like Vitalik Buterin are realizing, Coinjoin is the best privacy method for blockchains. Dash has the best implementation of Coinjoin in PrivateSend with several protocol level-features that means that no other coin including Monero can provide the same level of security, speed, and strength of privacy by anon set size that Dash can.
Vitalik Buterin Proposes Privacy Solution for Ethereum (ETH) Transactions
First Bitcoin Cash with Cash shuffle and now ETH seek to add optional privacy. There are several important takeaways from this information that have not yet been highlighted.
1 - Dash has basically won the privacy coin wars while being focused on other things. With a simple protocol upgrade dash increased its anon set size more than leading coins ZCash and PIVX with minimal side effects, unlike those chains which had to sacrifice some things like supply audit proof. Monero's privacy has been shown to have always been broken, and recently by a former monero developer it was stated to not work at all:
fireice_uk stated in his article, there's really no way to fix it.
I didn't say that. I think it can be fixed, however as is, Monero's (and all other cryptonotes') privacy is not fit for purpose.
The privacy coin wars began in 2014 with the release of Dash and soon subsequent release of Monero. Two years later, PIVX and ZEC family would join the mix. The Monero community being very aggressive, they launched an all-out FUD war on us. They had chosen a different strategy to privacy, one that would lead them to making their blockchain opaque. And now, as the PIVX, Monero, ZCash, ETH and BCH are forced to begrudingly acknowledge, Dash was right and did privacy right all along.
It might sound like bragging but its not: Its important to recognize both what you are doing right so you can do more of it, and also what you're doing wrong so you can avoid it. A lot of our trolls and competition want to concern troll us into only focusing on the things we do wrong, so that we panic and do self-destructive 'corrective' measures.
The best way to prevent that is to have a balanced look at what we're doing both good and bad. And the fact that PIVX and ZCoin had to shut off their privacy, ZCash would've but they fixed and updated the same issue with their sapling upgrade, and Monero has had the same inflation bugs and much, traceability1 2 3 proves that Dash's on-chain, optional obfuscation was the best and strongest of the privacy options.
The researchers also found a second problem in Monero's untraceability system tied to the timing of transactions. In any mix of one real coin and a set of fake coins bundled up in a transaction, the real one is very likely to have been the most recent coin to have moved prior to that transaction.
Before a recent change from Monero's developers, that timing analysis correctly identified the real coin more than 90 percent of the time, virtually nullifying Monero's privacy safeguards. After that change to how Monero chooses its mixins, that trick now can spot the real coin just 45 percent of the time—but still narrows down the real coin to about two possibilities, far fewer than most Monero users would like.
2 - The second big takeaway from this is that Dash was right to incentivize the masternode layer, because of that we can do our privacy the best out of all the coins that are using coinJoin methods, which is the best privacy method! That makes us the best of the best! Now you know why so many people concern troll about 'maybe we should remove privateSend guys'.
In a viral tweet, Vitalik Buterin recently stated in his latest criticism of XMR privacy protocol the following:
Vitalik Buterin Eyes Research on Privacy Coin Monero’s Traceability
Privacy schemes where the anonymity set of a single transaction is smaller than the entire set of users of the scheme are looking weaker and weaker with every passing month...Vitalik Non-giver of Ether

@el33th4xor Interesting attack on Monero traceability. Essentially, the attacker floods the network with his own transactions, and is able to remove them from the mixins later to identify other inputs. Costs only $1.5k for a year long attack. https://twitter.com/MihailoBjelic/status/1126878887886106629 …

Which shows that I was correct in the thread I linked below: Anonymity set size is the most important metric to measure privacy coins by. Which means all the hemming and hawing from the Monero community, trying to get that thread deleted, having me banned, calling me 'delusional' etc., is because they wanted to hide that information from everyone.
Indeed, Vitalik explained it exactly the same way I did:
In a follow-up email with CoinDesk, Buterin explained,
“Anonymity set is cryptography speak for ‘set of users that this thing could have come from.’ For example if I sent you 1 ETH and you can’t tell who exactly it was from but you can tell that it came from (myself, Alice, Bob or Charlie), then the anonymity set has size 4. The bigger the anonymity set the more privacy you have.”
The main thrust of my thread linked below:
So with no further ado, here is your simple guide to evaluating privacy coins! Like daily tx throughput is a key metric of btc/blockchain adoption and usage, privacy coins have their own 'key metric' to determine their ability to hide your tx history: the size of their anonymity set. This is basically the number of other people with which your transaction is plausibly 'mixed' so at to sever the link between your address and that coin. The greater this number is, the more difficult it is to associate a coin with your address, thus making it more private.
Before that thread, nobody except Amanda B. Johnson (and I only found out about her videos talking about monero's smaller anon set about a year after I started posting it in a more obscure video she did) and more 'esoteric' community figures were talking about the anonymity set size of privacy coins. Everyone used to argue that "Monero is the king of privacy because it uses encryption!" also, "PIVX is better than Dash because it uses encryption." When in fact, Dash had a much larger anonymity set than all of those coins for a long time (PIVX until recently and then it flipped again with Dash in the lead).
This means that Coinjoin is obviously the best all-around privacy solution if you want an auditable supply with strong privacy, and Dash's PrivateSend builds on that to rise to be better than any other offering on a non-Masternode chain.
Dash has 16 rounds of mixing with an anon set size in the tens of thousands to millions (it grows as more people use it) compared to Monero with an anonymity set size of only 11, and BCH of 5. Monero's anon set used to be only 3. Then it was 5, then 7. Now they recently bumped it to 11, but it was always really low when it had the most usage on darknets. See this thread I wrote on comparing privacy coins by their anonymity sets for a better breakdown
