Yobit manipulates its crypto prices. I have seen their programming do this...both create excessive pricing for no reason and then hold down pricing on currencies. BEWARE....STAY AWAY FROM YoBit. There are many other reputable exchanges to trade on 
Edit 1:I encourage you to provide proofs to justify your allegation or your claim will have no value. It makes no sense to create excessive pricing for any coin because if the same coin is available at a cheaper cost, yobit will loose customer. It's a bad business decision. So prove it and we all will be convinced!
Please note: I don't intend to defend yobit here because I haven't used their service and I don't have any experience with them. However, I am trying to challenge the mentality of falsely accusing any individual or business without valid proof.
