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.
Enjoy the profit, a crash does happen, sometimes even at an unexpected event like the pandemic, so always prepare yourself, and always get an update on what's happening in the market, and follow the coin you've invested, so you'll know the action that you are going to take, always get ready to sell and always look for the best coin to invest.
