Why don't you sell your Lisk coins at Yobit.net ? You will get 51 BTC at 0.017 rate instead of 7.5 BTC at 0.0025 rate..
Seems like a scam to me.
I can't sell it on Yobit, Yobit trades their Lisk that they bought on ICO.
So, if you think it's cheap, i can sell you at yobit rate and your known escrow welcome
