What do you think? I think I might be close. I'm guessing $10,000 per bitcoin by then.
If the price will be 10k per Bitcoin then you will become a millionaire but the real question is of the price is going to be 10k per Bitcoin. I suggest that you will earn more Bitcoins if you are serious about becoming millionaire.
bitcoin price for next 4 years will not go very high up to 10k. so you must have more than 100 bitcoin to become a millionaire, you have to think if that happened in 2020 bitcoin prices low
