Honestly, I didn't expect it to hit exchanges today. Being realistic with what I saw they claimed about the main net getting launched and claiming it would be launched the next day for several days straight I'm honestly surprised they managed to follow the timeline of giving exchanges the full node today. I don't blame them though, unseen things happen in new development and to say the least shit hasn't hit the fan.
You were dreaming if you thought an exchange was going to ninja-launch Waves because professional exchanges like Bittrex and Poloniex tweet coins they're adding or delisting in advance.
if they had worked together with waves team all those day's would be possible to lunch today!! when they list a coin they can announce it just few hours before the lunch !!
