Low volatility doesn't mean stable. Bitcoin has experienced periods of low volatility many times, however this doesn't mean bitcoin is stable, not even close. We all know it doesn't take much for bitcoin to explode, either up or down. That's absolutely still in the cards, I mean everyone is waiting for the next bull run and some people are waiting for a big crash.
It's like saying, this bomb is stable because it hasn't exploded yet.
Of course, Bitcoin cannot be stable in nature. It has only been for some time due to various factors that may seem stable in its price, but this is not at all the case. We have seen recently how Bitcoin has been raising and lowering the price of a thousand dollars in just a few hours. At any time, bitcoin can sharply react to the price of various news information.
