Bitcoin isn't a magic wand that we can wave around and make unemployment disappear. It takes more than BTC to solve the unemployment issue; a host of job creation policies and investment in infrastructure will certainly help.
I don't think the OP is by any means reiterating that Bitcoin will eradicate unemployment issues, but rather asking if Bitcoin could provide help in decrease the rate of massive unemployment in some countries. Have each government not been talking about job creation policies all along how well as that fare out ? Not so well, As far as I can tell.
Do you believe that the adoption of bitcoin in every country can less the unemployment rate?
Yes, it literally can and it is already doing so in my country, there a lot of young folks plying through the entrepreneurship route by buying and selling bitcoins in exchange for fiat and making decent returns than even an officially employed person. There are also big merchants who deals in cryptocurrencies that are employer of labour.
