Yeah, the coins dont has moved -and the good thing of not other exchange working is that there no place to go with they-- ,
so here the only problem at long is:
- if they would lost the  balances // user relations
- if they would lost the private keys

In this hipotetical scenarios we would need to organize as a community to get a solution, but there are not yet a proof to imagine this such big problems..

Meanwhile seems that a short term, who are in problem are the buyers, because dont there are yet Faircoins to sell
