It's a long story, but to summarize: hitbtc is trading futures on Segwit2 that was proposed then cancelled last year, this was a proposed Sha256 mod. Yobit issued "this" B2X to their clients holding BTC at the time of the fork, but they are not allowing people to deposit B2X onto their site, so effectively it is internal trading only. The only exchange where you can deposit and trade "this" B2X is Exrates, price at time of writing is $3.17. Well apparently there is a Brazilian exchange where you can put "this" B2X on, but yeah I'll let you decide if that's worth looking into. Bets on when "this" B2X becomes a penny crypto anyone?
