When we say "do not invest what you can't afford to lose" it's for that kind of behavior. Totally crazy because the market's so volatile, it can go down and up quickly. But even if it goes up, the thing is if it went down too much, your belongings could have been reduced to a point where it's approximated to 0 because some amounts are just too little to be hold on wallets, there's a limit, that's the main thing this crash period made me understand :D
