Do you believe that you would ever have too many bitcoins? It's never enough.
agree with you. even though you've been given a target per month to get 1 BTC. but it's human nature to continue to want more can not be beat. so my advice. collect as much as you can. according to your ability. try sincerity is a good thing to accept bitcoin as much as anything that you earn
I like this advice. I mean 20 years from now, 1 BTC would be so much.
I doubt your 1bitcoin is enough to retire in 20years, you must have 100bitcoin .
it's reasonable amount to retire in 20years
