"missed the boat" somewhat implies that blockchain technology is already being used for anything except the backing for pump-and-dump schemes and the punchline for jokes. Unless you mean specifically "missed the opportunity to make lots of money", in which case sure, that's absolutely accurate, but if I wanted to gamble I'd just go to a casino.
