Prime example of why idiots need to stop supporting these Russian IPO scammers.  This Sasha guy from waves is either too stupid to know that doing a market sell of 5000 BTC on Bitfinex will crash the market, or he made so much money from you that he doesn't even care how much slippage he causes while attempting to cash out for personal gain to buy as many Lambos as possible.  Most people here probably own more BTC than altcoins, so you're just hurting your own investment by supporting their IPO scamcoins.
