Bitcoin has many things to do with the current economic situations in different countries,some of these what bitcoin has done to the economic of many countries are -
first of all it provide employment and source of income thereby regulating the unemployment rate and increasing the efficiency of the economy.
secondly bitcoin could have hep many countries if they would have acquire some and make it a legal tender years ago.
thirdly it reduces crime rate in some countries because the reason for some of these crime is unemployment.
And lastly bitcoin rescues many families and individuals get rid of poverty thereby increasing the quality of life ,helping businesses,and helping the economy in different ways.
Bitcoin has really help the economy , this is just a nutshell of some notable works bitcoin has done to economy of many countries so i don't really see the reason why the government of some countries failed to make it a legal tender till now even after seeing what it has done to their economy.
Instead of using "economy of many countries", wouldn't it be better to just use "world economy" or "economy of the world".
Generally, I completely agree with all that you have said because my financial life is a very good example, many times I've mentioned on this forum that I used to work for a company where I resume work at 6 am in the morning and close work at 7 pm in the night, and on top of this rather unfair working hours, the pay was peanut.
I discovered bitcoin in 2016 and hopped on, and by 2017, I made my first thousand dollars, this was how I was able to quit from that company I was working for, I started my own business and till date, I've never had any course to regret coming into crypto.
In my country, the rate of poverty is very high, but the rate of crime have reduced even at this because, young boys and girls are now making money for themselves through buying and selling of bitcoin and other crypto assets, and through other means like airdrop farming.
Indeed, bitcoin and cryptocurrencies in general, have greatly added positively to the world economy.
