This is because the crypto community by and large also uses it like an investment asset, and not a currency.
> Negative interest rates in some parts of the world
This is to boost spending into the economy, and not as a result of currency being fiat.
> Ever increasing sovereign debt throughout the world, with no intent of ever paying it back
Sovereign debt is a problem, but it’s not solved by using an supply-limited cryptocoin. Governments exist for the people (corruption and inefficiency notwithstanding) and will create/spend money to build infra and promote the economy for its people.
> Lack of ability for 24/7 payments, or even instant payments
It’s good that you acknowledge a lot of these are USA-specific problems, because indeed, it’s possible to do 24/7 instant digital payments in most of Europe and Asia.
> No APIs for banks
Again, this is solved in EU (PSD2) and Asia (UPI in India). There are lots of apps that use these APIs and have created a burgeoning FinTech landscape.
> How do people here beat inflation
This is a social policy issue, and does need to be solved (not by currency changes though). The only people who worry about money vs inflation are wealthy people. Everyone else is trying to survive, and couldn’t care less about hodling crypto.
> proof of stake coins
These put early adopters and wealthier owners at an unfair advantage. Thus furthering wealth disparity. Even with fiat, the wealthy class can make good returns and avoid inflation, like you mentioned. The returns vary, but but so will crypto once adopted widely.
> reward for helping secure the proof of stake network
This is really wasteful. I’d much rather investments that support real-life industries, local entrepreneurship, or even just plain index funds that support the entire market.
> war on cash
I fully agree that the ruling class has been screwing over the average person, by devaluing their labor and greedily extracting profits.
But again, it’s a social problem, not one that tech like crypto will ever solve.
