Most of the traffic is on Bithumb, because there are no trading fees there, the same accounts have been trading back and forth in order to inflate the price, this is a giant price manipulation, the same thing happened with BitcoinCash recently...who can seriously believe that a Korean exchange could have 5 times the traffic of Bitfinex  

" Customers of the South Korean exchange Bithumb witness that, during the last take-off of the Ripple price, the exchange platform did not allow placing orders to sell below a certain level. One of the users of Bithumb published a screenshot from the Korean forum on the Reddit forum..."

Decentralized exchanges such as Bitshares & NVO are needed more than ever.

Bithumb price as of now ~$4 , everywhere else ~$2.5 ...IMH take your money and run
