Well with Bitcoin you need to think a bit wider than "just adopting it as the currency for a country". Bitcoin is already a world coin that is being used in businesses and alike an will create a much needed diversification for people and businesses ( especially the small ones) Bitcoin will exists as "that other payment option" (besides 99.999999999% of your paycheck is already digital ) So allowing businesses and people to create a diversification ( aka not putting you money in 1 or 2 pots) will generate a more stable climate. a more stable climate will push banks to give out better loans, which in turn will give the companies opportunities to evolve and grow, which in turn generate better/more job opportunities , etc
So bitcoin will contribute into job creation because it can have stabilizing quality.
