So I finally sell off all my bits of rubbish coins and sync my bitcoin wallet and the price goes up.... go figure.
It is easy to manipulate price on coinmarket.io
I mean if somebody now had like 20 BTC pump to 400 is possible maybe even more
It's equally easy to manipulate volume, and apparently immensely effective at making larger markets add you. (Judging by LeafCoin getting the Cryptsy add.)
Disclosure: I have some of those too.
