So I am not really into cryptocurrency and only have some basic knowledge. As far as I understand the idea between crypto (or especially bitcoin) was a decentralized payment system. Everything I heard about crypto the last few years was only about trading and value going up and down blabla. How is it going so far for using it as a payment method? Are there countries, systems, spaces in the internet or anything that actually use crypto for paying? Whar are some good examples? Do you yourself use some of these?
And are there maybe even PayPal-like Apps which you can use for paying in crypto to others?


Plenty of sites take crypto. Not as much that would make it especially useful, but keep an eye out.
I’ve been working with crypto for years and the fact that merchant services has been so neglected has been the most disappointing thing to me. Adoption is hard when everyone knee-jerks “scam” or they view it as too complicated and scary.
And since there’s no user-excitement, that kind of causes nobody to invest engineering time into building user-friendly systems for accepting and making payments. It’s just been more profitable to put that time into nonsense like trading, derivatives, and made up use cases for tokens.
VC money kind of ruins everything.
