A person will be surely be bankrupt in Bitcoin if they give too much confidence in this market without considering the too much risk. You should not easily to listen from the others like Bitcoin will sky rocketing and invest but rather search and review well the market movement first before engaging, its just like making sure you're right then go ahead so that you will not sounds regretting in the end.
Investor can get bankrupt if they sell at a loss. Simple as it is, just hodl. This is not permanent and I believe we can soon see corrections and recovery.
I believe this is only a disaster to investors who put their all in buying BTC when its peak and they have no other means of income and were forced to sell their holdings since they need to for daily expenses.
