With alot of BTC trapped in the LISK ICO until after april, i'm not sure we'll see that volume. I think alot of people were going to dump some of their LISK on the 11th to invest in the waves ICO.
But LISK is delayed, it won't be released on 11th April.. for those who wanted to sell a portion of their LISK to join the WAVES ICO, they still can, but without the bonus, unless WAVES ICO is delayed too or make another good bonus on May.
Why so hung-up on the Lisk ICO? That was like what $6 million? It's peanuts for the whales in the cryptocurrency/ICO space . Also, Ethereum's rise has given a lot more interest in these crowdsales, especially because people made a lot of money there, so they're liquid enough to invest in other projects.
