All those countries are barely 1 or 2 countries, not half of the world. I haven't been seeing crypto ads on fb since 2013, I've only stared seeing them for the past two months and that's it. I've just now checked and seen Parsec Frontiers, CRYCASH, GRAFT Blockchain... and that's just with the few scrolls down, so I'm not sure what you meant by "one of the major social media facebook stop all crypto ads".

No it doesn't. Bitcoin has $10k stable price and will be going up for sure.
