i have one question..
in 2011 bitcoins per 50,000 to 500,000 we spent for nothing, just pranking and stuff...
if one person kept 50,000 bitcoins in his account from 2011 up till now,
would the bitcoins still be valid for transactions?
Absolutely Satoshi is a rich man if he is still around alive and kicking.
Otherwise the supply is technically less than 21 million unless someone in the long run breaks the priv keys.
Absolutely yes, crypto wallet is like a bank for digital currency. Let say you bank fiat for even 3 decades it is still valid and due to demands fiat value increases so you become richer from that time span. But not the same sa bitcoin in real money(fiat) you keep it in 3 decades you'd become rich but in bitcoin when you keep it from 2011 you are now a god damn super rich baby.
