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)
