It will not crash once that it touches $10k, because you should know that there is a huge psychologic barrier on that price, maybe the price would be at $9950 - $9980 for a while, because it would be difficult to touch $10000, and the same happened when it touched $5000.
There is a huge wall on $10,000, but it does not mean that it will crash, i dont even think that there is going to be a crash because everybody is investing now to do not miss the big "bull run" during this days.
Join now, maybe you can make an easy profit with this bullish trend.
I think this is wishful thinking. You know there is a huge chance of it crashing right before or right after 10k.
