What are some counter arguments or criticisms you’ve heard about crypto that are valid?

In spirit of interrupting the echo chamber I’d like to know what discrepancies you’ve noticed in this space. I’ve taken a look at the Buttcoin sub so I could get an idea of how the other side think…but it was rough. There are a few good reads but you have to sift through the obnoxiousness and unreasonable rage they have towards crypto as a whole.

Obviously there are the obvious scams and memes and by no means should they be written off. But I’m mostly focused on projects that actually aim to accomplish something, whether it be real world or in the ecosystem of crypto. Think, the top 50 coins. The goal is to not view certain ones as perfect and possibly even clear up misconceptions about them.
