Bitcoin's rapid price development from 2020 to 2021 makes people feel a little crazy. From 6000 US dollars to the current 54000 US dollars, huge profits and capitalists attracted us. Overthrow the dollar hegemony? World currency? Block chain? Decentralized? , There is no substantive thing as a guarantee for this. To be honest, I also have investment, but only for profit.
If you're afraid it would crash, then don't do long term holdings because you may be frustrated when it drop so bloody. The rapid development was indeed a historical past which everyone of us didn't expect to happen. Hopefully we'll able to experience bearish market once again to have another opportunity for those who didn't able to grab their sustainable profit.
