Times without number we have been holding this view about bitcoin not posing any threat to financial instability as at today. Every entity making such claims only want to cause some rumble in the polity and looking for reason to lunch an attach on bitcoin for reasons best known to them. For an item to make any difference, it means it must be large enough to cause distortion which I am yet to see considering the decrease in the market price of coins generally at this time. And that is why a lot of company with huge transaction volume are not adopting crypto currency because they are practically not losing anything in their revenue base either in terms of customers or to competitors.

The movement of bitcoin always comes from the bottom. I think that the first to start accepting for payment bitcoin small online stores for which each buyer has value.
