I think that 99% of Cryptocurrencies are unnecessary and shouldn’t exist.
But I also think that if I want to buy a private VPN, any payment method except monero completely invalidates the VPN because now your credit card is linked to the VPN instead.
And I think that transferring money to family members abroad with some ethereum l2 curency is a 100 times cheaper and faster than any other method. I had to pay student loans in another country, but my bank blocked the credit card transactions because they were foreign. The only other way was cryptocurrency with a tiny fee, or a bank transaction with 10% plus 50$ fees. Guess which one I picked.
