Just wait another 6-8 weeks once the summer is over - the last quarter of the year is usually very good for crypto.
If you are both so far down on your investment I just don’t see the point in selling at such a big loss.
The current price for Decentraland is $0.35 and I expect it to at least be double that in the next few months.
It doesn’t take much for altcoins to fall quickly and it also doesn’t take much for them to pump quickly too sometimes so for me I will not sell and just wait for it to recover which I think it will.
I am not sure how high it will go but there is good chance it will at least double from current price this bull run so if you want to just take back what you invested just wait another month or so then you can take back your investment and move on to something else.
