Leave in your wallet those tokens that can bring you a good profit in the future. Now the situation in the market is not stable, so I would recommend to hold it.
i like to leave some coins inside of my wallet after I sell the coins because they coins leftover could be worth something in the near future.
in conditions like this I prefer to hold my altcoin because I believe the market will rise soon. but I think there will still be a decline back and sell it now and then buy it back when the price goes down is also a very good choice but it's too risky because the price might go up after you sell it. surely we must think carefully what we will do and get ready no matter what the results.
