Bitcoins is surely very dangerous. particularly to all the middlemen and other bankster parasites who need to start to think hard if there is anything they actual can do that adds value. Investing into business which trains former bankers to do something useful like electrician or plumber professions might be a good idea.
Hell no. Those professions require years of committment to master, and flooding those labor markets are going to crash the skilled labor value.
Come on!. Banksters are people too, once they cannot leach on every freaking single international money transfer, they are more than welcome to earn their living doing something worthwhile.
Only if they can learn to do it the same way that everyone else before them has, without a subsidy.
