Re: [ANN][DRK] DarkCoin | First Anonymous Coin | First X11 | First DGW | DarkSend+ Is Live!
What I am saying is that, since there is a .98% of any single transaction (as you have said) then given any 100 single transactions, there is a 63% that at least one of them will be discovered. This is regardless of whether the transactions are related or not, just any 100 single transactions at 1% should give a 63% chance of at least one of them being comprimised.
Those who require stronger anon, can and should use higher number of rounds than 2. This will force an adversary to spend too many resources for a miniscule success % that it won't be worth it for them to even start trying. And, if you (or your trusted friend) is running a masternode, in a future release you will be able to set that node to be a preferred one so it would always be one of the nodes through which the funds are anonymized. So I would say it would be a good idea to get a masternode if you don't have one by now.
Plus this:
Only applies if the coin source is constant. That is not the case in reality. Coins come from different addresses, which have themselves been mixed.
