It also doesn't add value in the first place. If you're a citizen in the USA for example, you probably have a credit card that you can use to instantly make payments either in person or online. If someone hacks your CC info, they don't get to immediately drain your bank account, and in fact usually you lose nothing after contesting it. The fees are generally avoidable, depending on the card. The only significant benefit that cryptos offer is a scheme that allows you to make payments without handing over your credit card number in case you're not sure some sketchy site is legit. So really, the big appeal of crypto was being the new Paypal. Personally, I would like an open source or federated replacement for Paypal that makes it easy to pay everywhere online without entering a CC, but I would rather not try and create and buy into a new currency in the process of doing so. Maybe something like GNU Taler can fix the credit card problem, but I'm not holding my breath on bitcoin.
