You will only getting panic when you are unsure to your investments because most of the people bought something without proper researching.If you really did research about your coins surely you wont invest to these shitty coins,and you will only buy the solid coins/project.What i did last bloodbath is,watch some movies and something different than looking your portfolio,my holdings will surely survive because most of them are solid coins,HOLDING will be the best thing to do when a bloodbath happens plus you can buy a lot of cheap coins when the market crashed surely you will make thousands of dollars from the market crashes.
