SEll your crypto and then invest again in the lowest possible market price for the crypto after the huge fall down. This is another way to earn more crypto even if market price is down. IT will not matter on the equivalent of that crypto to fiat even if it means that after the huge fall you can lose some of your money. This strategy is a better way to increase your crypto.
I suggest to still hold it. Dont sell it right now because you will add to the problem, if you sell it right now the vakue of bitcoin will drop so please dont do that. But sometimes we have incidence that we need money on our daily need especially in food, well its ok but dont do it everytime.
You're right. At this time, the best option is to hold your coins and wait for a better time, or even make new acquisitions at current prices.
