If you would have paid attention to Coinbase in the past, you would know that they are very slow and cautious about what they are listing, this alliance will be better for them and even help them decide faster than before.
Or practically, almost every international exchanges are like that whether it is they are asking a ton of money or legalization.
It has never been so easy for them to get listed on those big exchanges,
unlike those crappy exchanges such as Gravinex, CB and his peers that can be done as long as you have a few Bitcoin.
personally speaking, this is not a big deal. Because it is created to target those big shots and creating a source of income for SEC itself.
Bittrex is backed by SEC, right?
