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.
In many positive aspects, the presence of Bitcoin as a system has greatly helped facilitate many groups of people. The most obvious is privacy and freedom. The ease of transacting worldwide without involving a third party as well as low costs and a fast process are the first positive aspects of Bitcoin in my opinion.
As a job market and saving families and individuals from poverty, I think this can still be refuted because Bitcoin is only a digital currency system and in terms of price, currently only people who are financially capable can afford it, although it can still be done in a more flexible way.
