For some people, Bitcoin is simply more of a currency than a means of long-term investment, and it should not be surprising that some people mostly spend everything they somehow earn in Bitcoin, especially if we take the example of signature campaigns in which a large number of forum members actually have an additional source of income which help them to improve their standard of living.
If you have a job where your only source of income is Bitcoin, then you have to spend it to pay living expenses and there is no possibility of holding. Any other option where Bitcoin is just an additional income in addition to the already existing secure income opens up possibilities for long-term investment.
I personally don't feel sorry for any of the sats I've spent over the years, no matter what the price was then compared to today. It is simply wrong thinking that leads nowhere. Even if someone has an income exclusively in BTC and that is his only income, does that prevent him from saving at least 5-10% of that BTC every month?
