first of all it provide employment and source of income thereby regulating the unemployment rate and increasing the efficiency of the economy.
How do you mean op? I think you need more explanation to what you mean. No doubt bitcoin is a profitable investment that gives a good return in the long run , but this don't just happen so sudden , you must invest and HODl for long before expecting a thangible thing in return. But doesn't mean it's an employment opportunity which makes it a wrong speculation. Like something you can just venture in today and make money tomorrow. Bitcoin is not a free money making machine meaning
" no investment no profit". Bitcoin is not a charity organisation, or poverty alleviation program.
secondly bitcoin could have hep many countries if they would have acquire some and make it a legal tender years ago.
Yeah it would have been so, but time is never too late for any country to adopt it's usage since we are still in the early days of bitcoin below $100k
thirdly it reduces crime rate in some countries because the reason for some of these crime is unemployment.
There you go again mate.. bitcoin does not reduce any crime because it's not a free money. i guess maybe you think because of signature campaign that most people earn bitcoin from in this forum that makes it to reduce crime? I guess this is the aspect you are coming from, Well yes to an extent, but a criminal is a criminal bitcoin doesn't stop anything as a matter of fact most people even use bitcoin to scam people if you don't know. But I will leave it here let it not be that am criticizing bitcoin usage.
