It's pathetic that BitStamp became new Gox... and even worse
They do what they couldn't have been EVER asked in any country of the world (because bitcoin falls out of any control in any country), and yet they do it for 'free'.
Gentlemen, we need to boycott Bitstamp as they are playing dirty 'coin validation' games, which not only will devalue Bitcoin, but devalue any other 'blockchained' system.
We need to tumble our coins all and everyone.
If every coin is tainted then NO COIN IS TAINTED.
Go ahead and tumble your BTC, but you better hope like hell that when coin validation comes there will be a grandfathering for it. Of course if you DO have stolen BTC the calculus is inverted.
I've got documentation that all my BTC came through an exchange. I wired in fiat and bought at market price and can document both. I anticipate that this, at least, will be sufficient to obtain grandfathering. Relatively fewer people are going to have sympathy for those who actively attempted to mix BTC so I'm less confident that this will be grandfathered in.
While I am rabidly against coin validation, {color}-listing, taint, etc, I'm not about to take a bullet for others. Bitcoin as a system is simply not worth it at this point. You won't get anywhere near 'every coin is tainted', and it's meaningless anyway for anyone who understands how tainting would likely work.
Coin validation (and general loss of fungibility) will almost certainly kill Bitcoin eventually, but it could take a while. Those fortunate enough to be sitting on clean coins might have a sharp boost in their net worth as the 'dirty' coins are exposed and devalued. If just touching a tumbler itself turns out to be sufficient to taint coins to 100%, and it might be since it would simplify the math, that would increase the value of 'clean' coins in circulation even more.
