Bitcoin and ethereum blockchains are built to be open, public and decentralized. The difference between these and a bank could be compared to the difference between reddit and lemmy. Is reddit a scam? Perhaps not on a large scale but it has all the potential to become a scam once its executives decide to do so. Lemmy is not owned by a single person which makes it way more harder to “control”.

You can support lemmy by donating cryptocurrencies, they are not only used by scammers.

Most of crypto volume is done on bitcoin and ethereum network which are built to be less scammy than a bank. You could indeed argue that 99.9% of existing cryptocurrencies are scam because there are thousand existing projects that imitates bitcoin, similarly one could argue that 99.9% iphones copies are a scam

Your argument sounds like “pc are bads because of virus”
