What, do you think, the governments of different countries will do next to manipulate Bitcoin?
When you say government of different countries I just had to laugh as I just tried Imagining the government of my country "Nigeria" trying to pass a bill that'll influence the market globally either by creating FOMO or FUD which sounds unachievable. The top world power countries like China and US just like others have highlighted are the only countries which can successfully influence the market as they have done exactly that in the past.
Talking about influencing or manipulating as Op puts it, I think Nigeria can influence things
but maybe not necessarily on the crypto kind of things because is not a high tech country. It can be a contributor to manipulation however in crude oil production too. I think as the 6 largest oil producing nation with OPEC, manipulation is also not far from Nigeria too
On the part of adoption, I believe that Nigerians are part of the highest hodlers of btc in Africa at least. Therefore, a bill in the National Assembly for adoption of btc will cause a major spike in btc price across board IMO , even if it does not scale through (as part of manipulation)
