Time to move on and forget about it, with such a huge loss remembering your mistake will always keep you going back from time to time.
Best to continue your journey and accept this loss and find ways to try recovering those money from other sets of investment, learn from
this and avoid doing the same thing if ever you decide putting your money again to any project that you think will bring you some good outcome.
i know how it feels. it's hard to forget about the big losses and it's hard to accept it. but i agree. doing something is better than doing nothing.
try to recover your loss little by little. i know maybe it won't cover the loss fast from the past, but i'm sure, one day you will reach it.
