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?
He could be one of the millionaires in this technology if you had that numbers of coins. Yeah, nobody knows that the price will reach as high as $20k.
