Selling tokens right now is similar to buying near all time high. The price can not go much lower from here. I don't really think it is best time to sell now, don't get panic and get the best of you and be patient.
If we have a good strategy in daily trading our coin then it can quickly earn profit but in this fall down in market to avoid losses of coin much better to wait first and have patience until there's an perfect time to sell those coins.
