This isn't the type of question that will have a definitive answer and the future of bitcoin value relative to goods has an impact on the answer. Other things to consider are transaction fees and privacy.
My thought is that it makes sense to have different size UTXOs of course. You don't want one big one or many tiny ones. But what do you think is the smallest you should have?
My current thinking is around 100k sats. If you have smaller UTXOs now is a good time to move them on to lightning via a swap service. Am I wrong? What do you think?
