Btc-e and Bitfinex are providing margin trading, Stamp doesn't. Guess which exchanges see these huge drops? 1+1=2 people, if you can't connect the dots you're an idiot simple as that.
Nah... they're gonna argue..... how do you know 1+1 = 2!
Just like they saw the LTC buy trying to squeeze sell shorts but it failed, they still ask " how do you know"
