No bubble in Bitcoin and you will apologize for the second time, It's all about demand and supply. If many people sell their Bitcoin will be a correction, if many people sell their Bitcoin in huge amount will be a huge correction. But this correction will over and Bitcoin will increase again. You can see this situation in 2017. For people who buy in peak in 2017 and keep hold it already become a winner now, this scenario will be same if people keep holding it even though in a huge correction.

Holders always win, this is the point
