I really cannot see everyone in the country suddenly wanting to ditch their pounds/dollars/euros
One of the main things is, virtualy nothing is backing these virtual currency" fads" , at least the pound or most major currencies are backed with gold and foregn currency and goverment goodwill when the 75 year old little old ladies start exchangeing their life savings into bitcoin I will join in.
Even the major pension funds dont bother" investing" if you can call it that when theres nothing backing these "Alternative investments"
By the way , if you want to have a go I tip my hat to you , braver than me .
