Awful choice by Facebook @kthakur. If I'm into crypto or bitcoin, I most likely want to see ads about it. Who does Facebook think they are? I'm fairly certain they've also done this with medical marijuana, guns, and other sensitive categories. Apparently a Bitcoin company can't advertise on there, but they don't have an issue with Russia placing ads designed to stroke hatred & division within our country!
...or perhaps Facebook is getting ready to launch their own coin...?
