Thanks for asking, dawg.

Bcash, the implementation of it on coinbase, was a disaster, and an embarrassment to the community as a whole.

Rather than working to bring their fees down, they implemented a new coin.
Rather than caring about the ecosystem overall, they saw weakness in the network and capitalized.
I guess I can't blame them for making money, but I want to use an exchange that is at the front of technological understanding, not coin-hype and profit.

Also, Bcrash is a scam, and I bet I don't have to tell you why I believe that.
