EDIT:
Full disclosure and humble pie time.
Thanks to a very kind forum member who actually works in chip fabrication and has contacted me with some crucial information, we have to withdraw this. We've been told some wrong information, and by more than one source.
I would just delete this post immediately but that would be dishonest obfuscation. Not what we're about.
The app will still do plenty of other distributed computing tasks on PCs (as it does now) and on mobiles, but mining BTC on mobiles certainly won't be happening in 2014 and possibly not at all.
Apologies for the cock up. It was an honest mistake and we were acting in good faith. Hopefully this public retraction demonstrates that much, at least.
Cheers,
Mark
PS: For the sake of those seeing this for the first time and wondering what it was, it was an invitation to join our startup's Series A investment round, as we're growing quickly and raising funds to scale up.
Part of our startup's roadmap is a mobile version of our volunteer computing PC app: www.charityengine.com
We planned to use next-gen mobile SHA-256 encryption hardware - that's supposedly coming to mobile devices - to mine BTC. Wouldn't make much per device, but would be very efficient and we'd already have lots of mobiles running our app by then anyway. Hence we thought the BTC community might be interested.
That bit isn't going to happen. However, we are now looking at adding a scrypt multi-miner to the mobile version. Won't earn much per device compared to what they'll already be earning (distributed web-crawling for us, mainly) but, if it will work, we will certainly include it.
