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!
A sound strategy, the more it goes down the more you buy. Though only if it is a solid project. If it's a crap project on a temp pump it may never return to where it was and bleed forever.
