Nope, this is no existential question (although...). Everybody's talking about "When will Bitcoin die", but what if you die, and your family don't find your key, or don't understand it, or think it's only a useless sheet of paper with some code on it, or simply throw it away... Does this mean the currency's gone forever?
I find the possibility of this event rather realistic (yup I don't believe in eternal life), so that means that someday there might be 21M BTC but only 18M (and counting down...) is left in the market?
I hope that bitcoin will never die, Bitcoin is a big help for people who need extra money but there's a possibility that Bitcoin can die but a lot of years that the best cryptos in cryptocurrency industry market. What happens if we die? there's a two places we're go if we die heaven or hell and believe it or not everything will fade away and earth will pass away no forever.
