Steam used to accept Bitcoin, they stopped when the transaction fees made it unusable. Every time I remember that I get really pissed off, had the block size been increased back then Bitcoin would still be accepted in the many places it was (Steam wasn't the only one, lots of stores online used to accept it), but because they kept promising a magic solution that never manifested people lost hope and jumped ship (which did solved the problem as nowadays only investors use Bitcoin, so a lot less transactions, a lot more value in them, and higher fees matter less)

Can I send them an unmarked envelope with enough money to buy the games I want, with only my username in the envelope?

That would be cool.

But agreed, I think steam should accept crypto.

They had Bitcoin integration for quite a while. It was removed during a system change, probably because very few people used it

This is actually a really good idea. The people that want these kinda games are either underage horndogs on their parents computer, or able to use crypto.

Still waiting for NANO to become widespread 💀
