Then I hope you live eternally cause bitcoin will not reach that amount sadly enough, it's just way too high for it to get there the potential is not even there.
Realisticly we can talk about it reaching 2-3k if it's more hyper then the day today.
The 50k is about 80 times of the current value. If the price of bitcoin rise 40% a year, it will just take 15 years.
