What are your criteria for a successful crypto currency?Keep claiming that bitcoin has no substance and will fail "soon". Just because these claims have been made continuously for the last 15 years and failed doesn't mean that you won't be correct - one of these centuries.
As you say, it's been 15 years since BTC was launched. How many fiat currencies has it displaced? Which major retailers are accepting it for payment and how much trade are they doing in it?
Fifteen years and it is no more than a footnote.
