Sorry, but I disagree. Crypto exchanges are wonderful as they attract newcomers to the crypto world. Where’d we all be without exchanges? How’d we all get our first coins? Miners are the very small caste of crypto community so far as the majority simply purchases coins. Some exchanges do a nice job of simplifying the process of getting crypto for fiats. For example, my first crypto, which I obtained from CEX, was xrp (https://cex.io/xrp-usd). There are only a few buttons and clear instructions for newbies, so they don’t feel confused. Surely, there are some speculations but, c’mon, nobody forces you to trade! Let it to whales or experienced investors if you don’t like this approach. Don’t blame on exchanges, they are useful for the community.
