Huh, I would've thought that since people will pay over 300 usd for one Bitcoin Cash coin (according to 3 web sites I just sampled), there would always be plenty of miners competing for them.
OK, but I would've guessed that the reward for hijacking BCH's blockchain would be proportionally lower.
And please keep in mind the context of my first comment: I was replying to the assertion that the mere fact that Coinbase continues to let its customers trade in BCH is evidence that Coinbase is run by idiots.
The thing with those silly altcoints is that there really isn't much market liquidity. Even if you were able to steal a large number of them, any attempt to convert them into something useful (i.e. dollars) with crash the price.
Yeah, it's cheap to attack BCH but there's little benefit to doing so. Whether that makes BCH safe to trade or a reckless shitcoin is a matter of opinion.
