Yobit just enabled 5 more trading currencies, instead of only BTC before. These are now BTC, ETH, Waves, Doge, USD and RUR.
That makes it now possible to play with the much lower valued coins that were traded at 1 BTC-Satoshi before and thus mostly impossible to trade at all as there was a minimum transaction sum of 0.0001 BTC. Using one of the other currencies lowers these limits now significantly.
Happy gambling :)
