crypto has well and truly poisoned its own well here, with the sheer number of scams and fraud on the various platforms. It's also hella expensive as a way to take payments, since you usually have 2x exchange fees as well as the network transaction fees on a payment.
Crypto didn't do that. Investment bros did. Pretty much everything created after 2015 is a scam and hardly related to cryptocurrency at all. Just traditional investment/scam types moving in and adopting the name/language for popularity.
But you're right about the outcome from this. Most people don't know the difference, were only exposed to the post-2015 scams, and just assume all cryptocurrency is a scam.
>So why didn't crypto block or ban them from doing these scams using their technology?
And here we have a neat example of how this site, called "hacker news" of all things, can sometimes take on a absurdly idiotic hive-mind approach to some technology X where brainless hostility combines with laughable ignorance to reject something without knowing the first thing about it, even when the thing is emphatically a practical solution to a widely discussed problem.
