Bitcoin has been defined as a bubble at each of its growth, just as it was given to the dead every time it lost value.
It is clear that since this is something without a trend, and with a low volume of transactions, it has a very high volatility.
But I would say that - despite all the attacks - it continues its run towards a stable place in the economy.
Well it is true that bitcoin just suddenly popped like a bubble, we can see that in the past years bitcoin has gained value rapidly then when the people saw that it is mooning, people went crazy to get their hands on bitcoin, then it suddenly popped, so it can be considered as a bubble, but the thing is, that even it has lost lots of its value, it is still remaining at a great price and I think that is something a bubble could not do.
