Can I buy a pizza with it or pay my bills with it? Can my employer pay me in it? Or is it just an “emperor’s new clothes” thing? I just don’t see the tangible value in it. Rhetorical questions, BTW, I know you can’t buy a pizza with it, at least outside of some edge cases that I’m not aware of.
I thought what made money money was everyone agreed it was valuable and was willing to exchange it for goods and services directly. I don’t see that with crypto.
Crypto is mostly useful for extralegal activities.
You can technically donate for some services with it, but to acquire crypto you need to either KYC to some exchange which isn’t not only a massive pain, but there are very serious privacy implications with it. Or you can acquire it via other means which means you will be buying it at high prices.
Also note that most cryptocurrencies aren’t anonymous, every transaction is public in the block chain and can be traced back to you.
So if you really know what you’re doing you can use privacy coins as a tool to transfer money anonymously, but that’s pretty much it’s only real world application.
Also, from what I understand (I’m no cryptographer) cryptocurrencies use public key cryptography so quantum computers may in the future break all cryptocurrencies and well deanonymise all previously anonymous privacy coins transactions stored in the blockchains.
