This is good news for North Korea citizen as cryptocurrencies are changing lives and especially the poor countries like North Korea. North Korea's govt decision will make Korean people happy and healthy in the near future.
I am not sure about it.
The people there have other problems than crypto.
If they have enough money for a computer and an internet connection they maybe can profit from the rising of crypto.
But in the next future I think x10 at BTC is possible not more.
So if the people there would invest 100$ they could earn 1000$, not that much for a whole life.
we cannot know in advance how much bitcoin can grow in the future. if the technology can implement everything for which it was created then in the world there will be 90% of cryptocurrencies and 10 percent of existing money but in electronic form. and then bitcoin will be able to grow much more than 10 times
