There's at least a few more. "Bitcoin Gold" and "Bitcoin Diamond" come to mind, there's also something called "Super Bitcoin". They all seems like complete trash to me but somehow they seem to have a market value
This is probably the defining comment of this age of blockchain. :-)
Coinbase eventually distributed Bitcoin Cash but I haven't heard anything about Bitcoin Gold or Diamond.
I would just move original coins to different wallet first as I'm not sure if same transaction cannot be replayed on main bitcoin chain.

The story is more out of control if you hold the money in the trader. Since you had to rely on the trader to enable support for that new coin, which may happen later or not happen at all.
