Bitcoin is not a bubble.... We are very close to the stability of bitcoin price.....
This is true that bitcoin is not bubble but the other thing is true that bitcoin is not stable currency, price of bitcoin use to rise and fall often, with market demand bitcoin increase and decrease but it never get stable price. At the start of bitcoin people were saying that bitcoin is only a bubble that will bust very soon but that day never come infect people now accept the reality and the benefits of bitcoin very well.
I do agree with your that bitcoin Is not having any stable price but it is good for us, when we get the chance of low price in market we should buy bitcoin so that we can save it for long time and if we see the price of bitcoin high then sell at huge profit, this phenomena in bitcoin is very natural it does happen, so we cannot call bitcoin a bubble for it. Demand of bitcoin is now increasing so I prefer holding bitcoin even if you see the price of bitcoin not very high, because increasing price is very certain in bitcoin.
