I have a random question. I held my BTC on coinbase for a long time before I knew anything about forks. Since I held by BTC on coinbase at the time of the BCH fork, though coinbase didn't support the fork, where would my BCH end up? TIA
I'd assume they didn't support the fork and kept that BCH for themselves. I don't think you have a way of getting that back.
It's the downside of using web wallets; they get to control a lot of your functionality because you allow them to in return for ease of use. That's the reason many people say to stay away from web wallets. They can end up using their customers and exploiting them. Look into what Bittrex has been doing with their users, it's pretty disgusting.
