This is very simple to answer. HODL, don't do anything stupid this moment because the only thing that is best to do right now is to buy a lot of good coins in the market and hold them for at least 1-4 weeks and after that then you will be deciding if you will sell it or not. There is no need to panic because this is just a normal bloodbath.
its easy to say hodl but its actually hard for most of us including me to hold knowing that all coins are still decreasing especially bitcoin and they seems to become stagnant for a verry long time until now. in my case i cant really hodl for a much longer time because crypto is my only source of income right now because ive been decided to quit my job lately ue to the fact that i can earn much in investing and trading in crypto when compared to working outside for a minimum salary wage.
Well if crypto is your only source of income you should be buying and not selling right now. By selling right now you are only realising your loss from the decline. However if you buy now you are investing for future gains when the price goes up.
