Well, there is strategy called Average down! If you had been using the strategy you may not have lost so much. It is not late now. Double the units you have in all these coin. Any 10 % to 20% increase in price will automatically put you in profit! Keep buying the deep and you won't lose a dime at the end of the day!
Well for me average down is only applicable to the coins worth to keep but if it is just a shit or garbage coin this can only prolong your loss if you average down. I suggest you have to do research the coins where you invested if they have a good project maybe its worth to keep but if there's none you better sold it before it will drop deeper. better to invest in much stable coins next time to avoid this to happen again
