Thanks for the info! So the donation BTC are basically gone, and the donators don't get any XEL.
So where do the XEL people are pre-selling come from?
The donations were registered in XEL genesis block, and they are valid. The genesis block will be used for redeeming XEL once we have mainnet (hopefully soon).
Selling now is impossible - you can treat those offers as, well... market pre-screening :-)
If lite wallet will come up, those offers can be also used for OTC transactions.
