There is nothing special we can do, we just have to remain patient, and believe in better times.
Based on current market situations, the only things to do just wait but don't sell your coins at low prices because it's not a long time low it's just short time low and get your principal amount back and rest coins are free and sale them at any price that is your profit. And then just have to wait for high price or one more interesting strategy is if you enough balance to buy more coins at low prices then go for it and this step will make your buying average at low rates and if coins goes double then sale your half coins, Your thought?
