Can you provide some best practices during this chain split? Some things seem obvious like self custody, but I'm also hearing we shouldn't store too much BTC on a single UTXO. Previously I was under the impression we should be consolidating UTXO's. I'm concerned UTXO structure could be important when it comes time to move coins from the "bad" chain to the "good" one. Also, I have heard there can be privacy issues regarding both chains having identical wallet addresses, seed phrases, and so on. Any guidance would be much appreciated.
