> Cryptos are born out of criticism for current systems

Nope. Most are born out of people not understanding how existing systems work and/or looking to get rich quick.

> an ever evolving technology fueled by those same critics.

No, it's mostly a self-perpetuating self-congratulatory hype machine busily re-inventing the systems they criticise

> What doesn't make sense is when the other party starts making stories just to tarnish other competing technologies.

What does make sense is the extremely fragile ego of crypto bros who can't stand any criticism towards their scams and hype, or the mention of any possible issues.

All of that is correct, albeit not the full picture.

Crypto wasn't created as a "get rich quick". I say this because I was there since the early days and participated quite a bit on the related BBS. Back then you'd already make good money building bots for day trading on stocks, crypto was really about a type of currency that no government could touch.

Nowadays the large majority of users are desperate to make some money through pyramid schemes and pure speculation to "get rich quick" albeit they usually end up losing money. The small minority is doing what they've always done: looking at systems, criticizing systems and building their own solutions to those systems.

There is really good stuff being built. Not many do it, granted.
