Without an independent currency away from central bankers Scotland or any other country will not be independant.

If Scotland used BTC or any other crypto-currency I imagine it would be like the USA before 1913, with no federal income tax, no central banks devaluing the currency and less government trying to regulate everything and take peoples money by threat of force (taxation).

I may be wrong but other than a little Natural gas I don't think Scotland has many natural resources, So they would have to develop themselves as a place of inovation or a be a manufacturing or financial center to prosper.
