so coinbase/gdax didnt gave out bch or bcc to btc holders...so where did the bch/bcc went ? to coinbase pocket?
is it the biggest robbery/fraud in crypto history?
I do not think you can call it fraud, coinbase was very open about the fact they were not going to credit BCH to any of their customers and encouraged anyone that wanted to have that altcoin to get their bitcoin out of coinbase, if someone did not listen or did not attend the call then that is not coinbase fault also there is not a single proof they stole BCH for their own benefit, maybe it was a technical decision or one base on principles.
If this happened in any other industry, arguably it would be called fraud. The problem with cryptocurrencies is that regulators are behind the curve. Exchanges like Coinbase should absolutely compensate the owners of coins during forks. Anything less will simply breed public skepticism and the spectre of government intrusion to make sure the conduct meets standards in other industries. Coinbase should adopt a more user-friendly approach.
