Forget about everything else and just put everything on bitcoin. You are living with your parents, they pay everything for you, you got nothing to lose. If I was living with my parents, I would save everything and buy bitcoin monthly. If BTC doesn't keep rising you can still reach the 21 BTC holder group, then save this and retire in 10 years when the price makes you a millionaire.
Go all in on regret later. You are on a privileged position to profit from high risk high reward moves. No risk no win, and BTC is the best long term high risk bet.
I think, what you are suggesting is a good and a productive way of spending your youth, many youth today are spending their time doing nothing but the thing that they wanna do, and most of them ends up in jail or losing their lives so I also suggest focusing on bitcoin instead. You can never go wrong in preparing for the future.
