Edit: so if that is indeed the scam then essentially the claim of wanting the returns on ETH is saying that the mark deserves them because the gains were ill gotten via transferring the risk to the mark.

They would announce their miner, get massive presales in BTC, then 6 months later when customers are getting anxious they would start refunds. And, of course your refund is in the USD amount from your BTC at the price 6 months ago, not at current USD price. The miner company just stole your profits!
* Buy some of coin X
* Use that to buy some cash equivalent good that has a return policy (longer the better)
* If X appreciates by the time the return policy is up, you return the goods, collecting the gains.
* If X depreciates you sell the goods for cash in USD which likely won't have varied much in the intervening time.
* Repeat, and you will have effectively captured 100% of the increase of X while completely derisked.
