Interestingly, this what it is as far as exchange of cryptocurrency goes right now! Bittrex is having a regulatory nightmare in it's country and that has open door of unprecendented patronage for Binance!
They recently open their system for allowing users to buy cryptocurrencies through visas and that must be the reason why they are struggling now to cope up with their countries regulations. They badly needed such process to continue to compete with the new exchanges today which is more user friendly. The volume in their exchange still is considerable.
