I have invested something like $20k into bitcoin. If the price reaches even a tenth of its potential I will have enough to last a lifetime, possibly enough to support a family depending how high it goes. If it drops to nothing, I will be where I was a year ago, plus a much improved ability to save what little money I have. Either way, net win.
If the price of one bitcoin were to reach $10k or more, it would mean the USD had entered hyperinflation mode. The purchasing power of one bitcoin wouldn't be much higher than it is today. You wouldn't be wealthy by any Western standard.
Anyway: Bitcoin is still massively overvalued, and double digits will come soon enough.
