Money or Bitcoun?

On one very popular forum I have a second day in a row is a discussion with the apologists of shares and bonds, in other words market traders. More precisely, this is not a discussion, but an attempt to convince me that bitcoin and cryptocurrency is a bubble and risks. Argumentation is quite standard for such disputes, and lack of assets, and incomprehensibility of appearance, and inconvenience of use, and volatility of the course. Everything would be fine, but suddenly we got to the point that "bitcoin is a threat to the state", because each state must have its own sovereign currency. And then I realized one important thing, I think, the idea, people do not even admit that the existing commodity - money system can suddenly be transformed into something new. Moreover, in tone I realized that they are terribly afraid and worrying whether they will, these are quite advanced and economically savvy people are the first to start the cry of "don't let go. Forbid." That is, people were so flushed that even they are afraid to admit to themselves that a new time, a new and completely different world is coming. What can we say about the simple and not the prepared person, he's just fairly correct picture in TV and all, tomorrow is a rally call to save and protect.
Well, everything new made its way through the twilight of the deceased and the resistance, will not be an exception and cryptocurrencies. At least in the first stage of their conquest of the world.
