Apparently I am not alone in feeling foolish regards this. I think things are safe, but would so much appreciate advice. When using Coinbase, I had some small change in my Bitcoin Cash wallet, don't know how it got there, as I always use standard Bitcoin. Anyways I deposited into my Bitcoin CASH wallet. I then sent the Bitcoin Cash to a standard Bitcoin address, of which I have access to. So it has been sent to a one off address which is mine. Can any of you kind folk tell me what will happen?
If you sent Bitcoin Cash to a standard Bitcoin address you can still get to it (maybe).
There is too little to give you a fully correct answer. If the address is a wallet you control (not an exchange) then you should have a recovery password. It is possible to restore your BTC wallet into a BCH wallet, then transfer the funds from there.
I'm assuming you didn't accidentally send the coins to a Segwit address.
What would help the most, if you provided the transaction ID and the name of the wallet you use. (provide the path: Eg, Coinbase BCH > Exodus BCH > Coinbase BTC)
I can look into it a bit, make sure the tokens were transacted etc. Beyond that, i'm far more familiar about how to deal with this if you were running a bitcoin core node.
