If somebody claims that cryptocurrency is the future. Do not immediately label it a scam.
That's a very broad and vague statement.
Future of what?
Future of money? It is never going to happen. In the foreseeable future fiat will remain the future of money (the same fiat that is not even money). Cryptocurrencies will remain an alternative.
Fiat will still be Fiat and Crypto will still be crypto, and Crypto is always alternative or only optional. The main payments are still controlled by Fiat. It is still quite difficult to replace Fiat as the main means of payment, because in other parts of the world, Crypto is not allowed, while in other parts of the world, it is allowed with quite strict rules.
Besides, majority of altcoins are indeed scams and they have no future to begin with. Many of them are dying as we speak and being replaced by other useless coins.
Altcoins that are constantly evolving are just trash altcoins. Some of them survive and can compete in the crypto market, but many will just be forgotten and have no future. it will keep repeating
The technology behind crypto, which is said to be sophisticated, also needs to be questioned. Do they deserve to be said to be the future of payments by claiming to be the best? In fact, it would only be useless trash. The argument that blindly arises may be because too much crypto has come up with the scam label.
