Overall it fails as a currency, but does decently well on exchanges in spite of the inability to deposit.
You mean
because of the inability to deposit. Nobody who wants to dump their Bitmain Crash coins can send their coins to an exchange in order to do so.
Not only deposit, but actually move the coin elsewhere.
Needs at least two steps (1) move coin into a new BCH address. (2) move coin from BCH address to exchange. At 11 hours a block, that will take quite a while to happen!
