step one:set up a site that looks legit
step two: make it a pain to withdraws with google authenticator, so people keep coins in it
step three wait for a coin with mega hype
step 4 bee the first to exchange it bringing tons in
step 5 close down account take coins as soon as vircurex opens up
step 6 sell on vircurex
I feel this would just result in a massive crash in value of the coins, I don't believe anyone could make a particularly meaningful profit doing this so early in a coins history. This is however just my opinion.
Even if you count the FC as worthless, a lot of LTC got deposited there... that's REAL money!
