Not really. You should have many utxo with many different amounts. 1M, 3M, 5M, 10M, 21M. Each one will be used at a different moment you need.
Example: you need to open a 5M sats LN channel. You will not use a 21M utxo or 2utxos of 2M + 1M, but a 5M utxo.
You get it now?
So leave that utxo as it is now. Start building new ones.
Thanks Darth!
