Well that depends on if you currently spend bitcoin or if you’re stacking. For everyday use 100k is a good size, but imo it’s a bit small for stacking. I would personally consolidate into utxos of at least 1M sats. This number may be different for everyone depending on your means, but my thinking is that it will become increasingly difficult to stack larger UTXOs (relative) in the future when price goes up, so might as well stack those larger UTXOs now when you can. Also if you’re going to be stacking or earning bitcoin for a long time, you can quickly end up with a lot of UTXOs you need to manage
