Would you say its more than even say 50 max? There are over 2k cryptos. Most are worth nothing. But how many are actually worth something?
Some of them are having a working product but they are still can't get a lot of attention from speculators. I guess it's no more than 200 crypto. Some coins in this list can be categorized as zombie coin too.
But a lot of them are still trying to find the solution to not pegged with payment gateway companies just like VISA.
