My opinion:

- Consolidation of UTXO < 1 million sats is a must

- Even 1 mio sats might be too low for long term (I prefer > 5 mio)

- Never consolidate kyc with non-kyc UTXO

- if possible consolidate UTXO from same source

- Having multiple different UTXO sizes depending on your stack is a good solution

- Coinjoin gives you privacy for future transactions but doesn’t affect past transactions

For example UTXO split for 1 Bitcoin:

1x 0.25

5x 0.1

5x 0.05

For 0.05 not being economically spendable, it takes an insane fee increase. On native segwit it would cost you ~80 k sats at 1000 sat/vB
