If there are miners out there willing to take losses in BTC for the sake of $ gains, my offer still stands: send me 100 BTC now and I promise I'll send you back 60 BTC once the value of BTC doubles. No hassle, no electricity cost, no hardware failures!
That service of yours is not that off the mark. I mine for two reasons. One, I used 0% interest credit to buy the miners since it wasn't feasible to buy BTC directly like that. And second, mining keeps me from selling on short term profits.
I've been selling my coins pretty much as I mine them and use the money to buy on big dips and then jump out quick for some more gains.
My goals wasn't to get really rich, just double my investment. That is going along fine. And yes, your service would be fine for people like me with quick trigger fingers
