Well let's face it. LE and the feds know what I'm guessing 90% of Bitfloor (and similar operations)'s deposits are for. They know, we know, and Bitfloor knows these bitcoins are for purchasing drugs. There's no beating around the bush about that. The issue is they can't prove it due to the anonymous nature of this entire shindig. If you withdrew $152.57, and then deposited $152.57 into their account 10 seconds later.. it's quite obvious it was you who deposited that money. Even if you withdrew a little more then your Bitfloor deposit each time.. with the proper analysis and time correlation they could probably say with 75% probability you made that deposit. I don't think that's really a problem though, because it's not worth the time to try to "launder your own deposit" you know? At the end of the day even the $152.57 simultaneous withdrawl/deposit isn't a crime. You're buying bitcoins. Nothing illegal about that. It's what you do with those bitcoins that violate laws.. but again, can't be proven. Now, true, you don't want direct transfer to Bitcoin companies tied to your account because that's just an unncessary hassle you might have to deal when (NOTICE I SAY "WHEN", NOT "IF") the feds shut said bitcoin trading company down. It's not an IF. It's a bet-your-ass WHEN. I am willing to bet you all these bitcoin traders are being watched and surveilled at every level from who comes and goes into their offices to the tax returns of the company and whatnot. If you think the DEA/IRS/FBI/ don't have a raging hardon for this entire thing you're living in lala land. One by one they will all have some trouble at some point and you don't want a knock or a call to "chat for a few minutes".. hence, keep your name/credentials away from the bitfloor companies at all costs.My philosophy is - be discreet (but not super paranoid and take 2 days concealing your own withdrawl only to deposit it anonymously as cash into a bitcoin trading account), be efficient, and enjoy this party while it lasts.. because it won't last forever.
