Believing all the cryptocurrency ecosystem is a scam is just a big indicator that you know nothing about it

The main thing is to have a trustless currency that is decentralized (can’t be easily censored), and that isn’t owned nor controlled by some centralized organization (ex: a country). Its uses are best seen in countries where the government goes bankrupt or fucked up the currency by printing a lot of it, or for currencies that no other country trust

It will be niche and useless to most people, but it’s a verifiable way to check money is not being tampered with. It’s also the best way to transact online anonymously or pseudonymously, and not relying on a company that’s trying to make as much money as possible

Due to the way some cryptos are, they became a speculative investment. The fact that they’re not well known increases this use. Some cryptocurrencies are designed to be inflationary. Some are straight up pump and dump scams, like a lot of things. There will be assholes everywhere
