Obviously what size UTXOs you keep will be different for everyone given everyone will have a different sized stash, but it’s considered good practice to have a number of different sized UTXOs in your wallet.

This is similar to how you probably don’t just carry around one $100 bill in your actual real world wallet. You instead probably have a few $5’s, a few $10s, maybe three 20’s, some coins or some sort of mix of big and small denominations in there. The same goes for your Bitcoin Wallet.

Don’t just have a single, massive 1 BTC UXTO, have a few 0.1 BTC, a few 0.05 BTC and maybe a 0.5 BTC UTXO as well. Like everything in life, you need a good balance.
