I have proposed to save 2 bitcoins in the long term to see how much value it could reach and see how financial systems in the future can start using only bitcoin in fractions instead of fiat currencies.
My estimates are positive, I think that in about 10 more years, Bitcoin could easily be worth about 50 thousand dollars.
With two bitcoins in 50 thousand each, they are 100 thousand, if I sold them at that price I could acquire the following material things:
1 medium mansion
1 luxury sports car
More than 3 years of good income and good food
1 small yacht
2 animal farms
3 fast food places
I think if I could get that and I would still have enough left over, now if the financial system is updated enough, paying in btc fractions with the price of one to one would be more fair and original.
