Well in all honesty. Banks all over the world are afraid of not gaining into this kind of transaction. Many people are tired of putting their money into savings that don't even earning a lot of interest. In addition to that only the managing banks gaining from this and getting wealthier. The target of this crypto currency are those small people that want something that is earning and looking forward to the future. Majority of the population of the world are middle class. I myself wanting did not have a silver spoon when born. However, wanting to have a better retirement. I hope my investment in bitcoin in the next few years will flourish. Again in this type of currency. Invest only what you can spend. Not all of them. Alyways have a back up plan.
