huge list of assumptions there, but having read your responses you dont really understand bitcoin, transactions or tumblers. Tumblers can delay sending transactions by anywhere from hours to days, so matching 1 input with 1 output would be dificult at the very least. If 1 input is split into 6 outputs of varying sizes, sent at various times how would a beefy server help you. Say I send in 10BTC to a tumbler and my output is split into 6 outputs of between 1 and 2 btc each, these are issued to different addresses over a 5 day period. How do you trace that in amongst all of the other several thousand transactions that occurred in that 5 day period? I would genuinely be interested in how you think this would work, as would many in law enforcement and the bitcoin ecosystem.
