Bitcoin!!! Also change your name on your 18th birthday. No one will know unless you tell them. Amazon hires anyone. Work there, apply to a housing lottery, drop out of high school, be free. Get a GED if you really want to, with your name on it and not ugly ugliness.
This comes up a lot. The fact is that almost everyone who mined a few dozen BTC back then would have sold it when it reached $100. No one ever thought back in 2009 that it'd be worth what it is now.
I had two giant servers sitting under my desk when bitcoin started up. I was trying to decide whether to put them to work mining bitcoin or using them for seti at home. Well I decided to go with seti. And I am actually complacent with that decision, because had I got into bitcoin I know that I would have some sort of anxiety over when I sold, or what I paid for something like a pizza. I know those people who are searching trash dumps for their old hard drives are just in a weird hell that I am glad I never put myself in that situation.
You know.. years later I did the crypto say trading bull shit.
I made like $5k but the "cost" was horrible. I didn't sleep well.. always tracking things on my phone or computer. Afraid the bottom would fall out and I'd lose my small fun money.
It was absolutely an awful experience.
