afaict the only reason to do a test transaction is that you're concerned about the entropy of your private key and want to see if it gets sniped. Otherwise, so long as you're doing typical best practices things and verifying addresses match, there's not much point in doing a test transaction.

I saw a thread on X mentioning the BCH liquidation. These forks are like dividends, so it makes sense to liquidate them. It's what I'd do - ideally before the novelty has worn off.
