Good for them, they had the opportunity to buy early and be able to sell at $100k which many individuals can only dream of. Bhutan is a small country with a population of less than 800k, however, its economy has been on the rise. The economy of Bhutan rose around 6.1% in 2024 alone which is a great feat to achieve, in my opinion. Many countries wouldn't be able to achieve that.
Now with Bitcoin providing them with good profits, I'm sure they can do better things for their economy that many other countries aren't able to do. Some countries, mostly third-world, aren't able to understand and realize the potential Bitcoin has and they are truly missing out on what Bhutan and some other countries are achieving utilizing Bitcoin.
As far as I know, most of their bitcoins are from mining, not buying. Bhutan has abundant hydropower resources and they have been using that to mine bitcoin since 2019 and have become one of the top 4 countries holding the most bitcoins in the world.
Not every country has the advantages of Bhutan and with a small population, governance is much easier than countries without resources and a large population. So don't be so quick to criticize other third world countries for not investing and not intending to invest in bitcoin because they have hundreds of other important problems to solve.
Also, this is the 3rd time they sold bitcoin this year, not the first time.
