I believe that if the currency, for example, is provided by the economy of the country, then bitcoin is not provided. That is, it is likely that it can be a soap bubble in terms of value, which sooner or later burst.
Bitcoin is really doing well for itself at the moment and whether we keep calling it a bubble or not, it keeps soaring. The last correction despite all the FUDs generated with bitcoin being a bubble should have gone further down than that but here we are; it keeps soaring. Should we call it a strong bubble that has refused to burst all these while despite all that is being said? Or should we still keep watching if it is really a bubble or not? We just have to keep watching how events end up turning out.
