Bitcoin bubble will continue to blow bigger and will no burst in the next two generation to come, that is what make it different from other bubble in history. Bitcoin is here to stay and I will never refer to it as a bubble because it is not bitcoin is a currency traded on so many market around the globe with decent value against other currencies.
It is not correct to speak about Bitcoin like a bubble, as bubbles burst always. As you say yourself, BTC will not do it in the nearest time. Soon, crypto will be recognized as an alternative currency.
