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?
I have different opinion on this matter. I think if all Bitcoin holders at that time (2010) just hold without spent (using) it, Bitcoin could be useless. Present value is determined from the past action. Bitcoin reach $10k price along with its stories, such as pizza day, Cyprus banking crisis, and other countries with "trash" fiat value. You may argue with gold case when it mainly uses for store of value, BUT gold has a long history of being medium of exchange.
