Whether we like or not , at this stage you don't have any other option but just hold. if you are not very new to crypto that means you have bought coins for higher price than now, then you cannot sell at this at all. so lets HODL.
It needs to be made bold here that Hodling is certainly not one and same as trading, as any experienced trader would have well before now cut short their losses and now buying back the coins at cheap rates and most importantly with peace of mind that bottom has been reached or no longer afar off. If it takes for instance the next 2 years for a market to make an new ATH, any serious trader should by this time have multiplied his funds beyond what mere Hodling eventually gets to serve.
I think it is very safe and profitable to hold patiently in this period of bear because selling now will also be at loss but if you hold patiently and even buy more, when the market recover from the fall, the price of the coin will also grow.
