Probably would do what I would have done before bitcoin was invented. Oh wait, I was a teen who had no financial responsibility or didn't care about anything haha.
If bitcoin wasn't here, probably would have invested in the "regular" things like most people do like stocks or metals.
if no bitcoin:
2. do not know the development of digital finance
3. can't transact across the border
4. Can't have big finances
6. Unable to know the world news which is full of market manipulation
7. will not know what FUD, FOMO, TREND, and other things related to digital money are.
and there are many things that we cannot mention here. plus during covid 19, maybe we will just be unemployed, not sure where to get income during the lockdown that is still in effect in my country.
Except 1 and 5, you could do or know literally everything even if bitcoin didn't exist. FUD, FOMO and Trends aren't a bitcoin exclusive thing. And if you found work paying in bitcoin, you could have found work paying in fiat.
