I honestly don't see how any country would embrace BTC. If they lose control over their money printing press, they will be extremely limited in how they can govern. Its all about control, and without the printing press at your disposal, its very difficult to control the population to their satisfaction. It would of course be very wise to get ahead of the game, but I think that since its against their primary plan, they will only get on board when its far too late.
I do have a concern though that the distribution of coins at the moment isn't done in such a way as to give most people or countries the incentive to really adopt BTC. Studying about all the crypto projects, I see how important it is to take into consideration how much is pre-mined in advance, and how much is reserved for the VCs and others on the inside. When you get to numbers like 75%, which some of the coins have, this is insane, and makes the project more of a pump and dump, but even 30% is high. BTC is of course more pure since there was no pre-mining awarded and Satoshi himself had to the mining for his own stake. But to truly switch the world to a bitcoin standard, I'd like to see the distribution be a bit more equitable. There is no incentive to switch to something new if you don't have any and someone else already has a pile of it. So in a way, its needs to be more attractive if you're gonna get most citizens on board and eventually the central banks.
Everyone compares the adoption of crypto with either the internet or cellphones. But in both of these examples, its not like starting late somehow hurt you negatively while grossly rewarding an early adopter. If you used the internet for the first time in 1995, perhaps you have way more experience than the guy who finally bought a modem in 2000, buts its not like the guy in 2000 had a negative experience because of his late start (if anything, the modems were cheaper and faster). But with bitcoin, starting so late, lets say with BTC at $1 million, really impacts you negatively. You won't be excited to get on board like you would be to finally buy a modem or buy a cellphone, but rather, you'll be pissed off for being so far behind and poor compared to all the others. For mass adoption by individuals and countries, I think this will be a big enough reason for why there will always be the search for a new coin.
