Most of bad rep is generated by insufferable hype train enthusiasts we started to call cryptobros and big tech CEOs trying to capitalize on putting this edgy technology everywhere, just like with LLMs right now. Many people who escape shit states in recent years legitly use cryptocurrencies to bring their unconvertable money abroad and that's more reliable than a suitcase of precious metal bars, lol. This tech is no Jesus or Devil, it just needs to mature and overcome the initial fascination, with most bad realizations and schemes dying off. In ten years this discourse would be very different.
