Almost everyone is wrong, and only because; Bitcoin is not at all about all the deep dips but the stabile growth with the high peaks. That's it and that's all of what most of them just don't get.
Not all the time does the market pump and people get profitable still some corrections need to be executed because if the market gets pumped continuously for sure once it reaches the peak of its price there's a crash market will happen and its unhealthy, and we know how bitcoin dominates the market for sure most of the pairs will crash too. Bitcoin already created a history you don't need to get bothered too much with the market price its part of it becomes volatile. If you don't trust the Bitcoin potential possible you will left behind after its sky rocket.
