So I logged into coinbase after a while of not mining to set up a rig once again last night. To my surprise, I have a BCH wallet in my account now (I know they just added BCH trading). But what is weird is I have funds in it? It shows as receiving ~$67USD worth of BCH on december 14th, which has since doubled in value. It says it came from a BCH address, but does not list the address and does not have the transaction details like BTC transactions on CB have. Any ideas?
