Is coinjoin anonymous or not?
Not really, CoinJoin on Bitcoin's network runs on a few centralized servers and has only a few rounds of mixing. It is what i call low level anonymity.
Also CoinJoin has limitations that few users realize exists.
There is a difference in how Dash uses CoinJoin and how Bitcoin uses CoinJoin.
Dash provides a higher level of anonymity through more rounds of mixing and having a decentralized network of servers then Bitcoin, if users take into account the limitations of CoinJoin.
So dash has a better version of coinjoin..is this better version of coinjoin anonymous or not?
Now, "level of anonymity" means nothing, either you are anonymous or not..if anonymous, then delist.
