edited to add: never thought I'd have the opportunity to buy in at these prices again. It's been great
18k actually
Price is still 21k on Yobit with at least 5-6BTC of buy orders above 18k - looks like a great arbitrage opportunity for somebody with a large amount of BTC to spare on Poloniex (I'm out of funds for now)
Lisk wallet on Yobit is under maintainence - that would explain why =)
