The main advantage of Bitcoin is fast transactions. It will let the economy to gain its potential and evolve. Being hard to earn is also among the pros because it makes Bitcoin valuable and accepted.
Despite that fast transactions, people don't usually use Bitcoin.
Also, I think it will not make the economy develop or evolve but with the help of blockchain technology, it might be of help in a way for the country. It is valuable but that doesn't really matter since as long as a small population is using it in the country, it will not matter at all.
