You gotta see I'm sceptical.
Please tell me I haven't made the biggest mistake of my life?
If by biggest mistake of your life you mean the choice not to get in on bitcoin sooner? better late than never! this isn't even 10 years old yet. just imagine in 5 years... there's so much going for bitcoin lately that it should just keep going up long term
It may be late to have the earnings of early adopters but it is still not too late, bitcoin has not been adopted globally, you just need to run some numbers in your head and you will come to the conclusion that bitcoin can still go up a lot, for example if bitcoin has 10 million users and we assume that in the future at least 500 million people are going to use bitcoin then the price could go up 50 times, you will only need a handful of bitcoins to become a millionaire.
