in 20 years 1-2 BTC will be enough to retire on.
Dude you realy think it will be enough i mean i want to have at least 20 just to be sure
Thats not enough. It depends on requirement. For sure you have 20years more. So that can have a try to get 5bitcoins every year which will count to some 100bitcoins which is more or less enough based on your necessity.
Wrong. in 20 years, bitcoin's value will either be high (say $50,000+) or very low (say under $100).
In either case, you won't need 100 bitcoins because it'll either be not nearly enough, or you will need much less.
not necessary we know only how many halving will happen
if calculate halving now (20 year with 4 year halving period we have five) price will increase let say 50% each time
it may be around 2k in price we dont know now will influence economy or will it be recognized as fiat currency if so they may be even higher
so my estimate is 2-3 btc a year in this scenario in years around 50 would be fine
