I'd expect the plastic to just meld off that thing like butter. I'm absolutely no expert on chips and hope they wouldn't be stupid enough to let that be an issue, but it makes me a bit uncomfortable.
By the time these issues are resolved (if ever) your 5% will be history. More like sub 1%. You know the rate of difficulty increase don't you?? ATBEST this is a big risk and until you SEE the hashing .001 is a really good price. No joke guys see sense. My last shout on this today. Don't say you were not warned.
