Ideally you should keep them, for now if selling is an unwise option. We can pray by 2022-2023 maybe these cryptocurrencies can grow back to the value it once peaked. The global economic market has not yet collapsed so we should not pray that crypto can grow steadily.
I agree with you in 2022-2023 that's why hold is the best solution, if someone will add assets to the future at this time is good to buy not sell
It is best to buy only with a reasonable plan. The last drop is an opportunity for us to own crypto at the best price in 2019 for altcoins and for Bitcoin and the top 30 cryptocurrencies, this is the next opportunity after we missed in early 2019. Next morning I feel the whole market will increase steadily to create a jump in the coming years.
Treating every dropped price in the market as an advantage for the investment is not right, the consequences of the bear market still affect the investor confidence. The average market entry price is important and dropped market prices provide a good opportunity for adding more bits to stash. The best moments for entering the bull market is the last months in bear market. Sitting tight(no-trading) is the hardest task of the impatient crypto trader.
In my own opinion, we should actually HOLD token no matter what happens especially at a time like this knowing that the market is on a downfall it is really not a good idea to sell tokens in a situation like this because you are wasting your money if you do that. I believe that the market will recover soon, not now maybe but I believe that it will happen, just like what happened last 2017, wherein the market really pumps up to its highest peak that makes every altcoin on its high value also. Have patience because it is actually the key for you to gain profit in the future.
