It does hold --SOME-- value, if you make a sum of all the BUY orders currently on YOBIT, you see the total is 0.10244642.
If i'm informed correctly, the problem with this coins is that you're not allowed to sell your YOVI unless you sell it at at least 0.00001 YOVI higher than the current price, but only 0.01
BTC worth of YOVI can be sold at any specific price.
At the moment, all pricepoints under 0.001715 are taken.
At 0.001715 BTC/YOVI, you're allowed to sell around 0.2 YOVI
At 0.001735 BTC/YOVI you're allowed to sell less than 0.01 YOVI
...
Even then, at the current trade volume of 0.02
BTC/24hrs, it'll take the lender months, years, (never),... before he gets his slot for selling off his collateral in case you default.
I feel bad for you... I fell in the same trap, but eventough your YOVI might not be worthless, they're unsellable
