i think after he saw that he couldn't compete with others exchange he scammed everyone
otherwise all those efforts for a few btc, seem a waste of work...with fee his profit would have been greater for sure..
hmm i used sharexcoin for many times before
it was good exchange, we can see many feature, i'm sure this exchange will have great potential to become big exchange
but ziplibrary can't restrain himself after see many BTC volumes from qora trade, and stole our coins
imho
