Yep, I got the news this afternoon. $400 million, not cheap. Let'see if they plan to improve the ghost support system as I remember users were complaining about it. You can almost be sure to see KYC verification if there isn't any already.
for Circle $400M is not much they are earning a lot more and entering the exchange market it will boost their income more this is good news for Poloniex users because the Circle is big influence for Cryptos trade and it may help it going back to the top alongside Binance and Bittrex it's not going to be easy to get the users in time but good publicity and media will help it get back out there fast off course they need to bring something to the table to make it more appealing to use Poloniex over other exchange platforms.
