Technology

Amid all of this, nobody has managed to give me a reason why I would want to use crypto for transactions instead of my debit/credit card.

Crypto doesn’t come with any of the consumer protections I expect from my current payment methods. And in fact, it is designed to make some of them literally impossible (I.e. chargebacks). This might be appealing to sellers, but financial transactions are a buyers market. Sellers hate dealing with PayPal, but they put up with it because consumers trust PayPal and demand to use it.

So right now, crypto has these problems:

1. It is riskier to me than my current solutions.
2. Even with PoS, it is an order of magnitude more energy intensive than current centralized solutions. The the energy cost for just McDonald’s to replace all their credit card transactions with Ethereum would be staggering.
3. Most importantly, it does not solve any problems I have that other solutions do not. There needs to be a reason for consumers to change their habits. You can’t build your sales pitch on intangible benefits that are only relevant to a tiny minority.

It’s been over a decade and blockchains are still a neat technology without a useful practical application.
