Of course there are many factors to consider including how much you have in total and how much a given amount in sats buys you in the future.
I'm thinking about having to spend without revealing too much to the receiver in case privacy advances aren't what we might hope by that point. In that case I might want to have less per sending address.
However, if fees are too high then small balances won't work. Is a million sats too high or too low? 5 million? Again, I'm not at all thinking about where I keep the bulk of it.
I'd really appreciate anyone that has mulled this over offering their thoughts.
Edit: Whenever there is an increase in "blocks to clear" sustained for a few days it reminds me to think about how I should do my best to prepare sooner rather than later.
