yeah, that is a sad story and a lesson for us to be more careful when investing in crypto currency and we have to know the risks, don't be too greedy to get profit when there is a chance even if only a little
I don't know I just wanna talk, if someone gets a loss when investing in cryptocurrency like bitcoin, just hold. Look at the bitcoin nominal you have, even though it decreases, the nominal will not change still remains the same which decreases only on money fiat. And sure enough, when someone wants to invest in bitcoin then he must know the function and potential of bitcoin in the future, if he understands it well then they will continue to believe bitcoin will have a high price in the future.
