Part of the money I have invested in new projects, and spent the second part on the family. And how did you manage your earnings?
About 90% of my earnings I spend to cover my family's living costs. Other 10 go for crypto investments, trading experiments or simply holding btc. There was some time when I sold everything I earned and didn't care about the prices and btc's potential. Then I started caring and was holding btc when the price was like $15k, so now I kind of regret it but keep holding and hoping better.
If you really believe in crypto, as most of you obviously do, I'd recommend to not spend your earnings. In 10 years, you will be happy if you've invested everything in solid projects.
That is most likely true, but the problem is that from time to time we need the money to pay for the bills and stuff like that. Unfortunately, this really makes it hard to hold and wait for that time. And, you know, it can also never happen and we might turn out to have indeed been in the bubble all this time.
