Could you make an accurate list of things and their cost (and your profit if there is any) that constitute of the 3 BTC?
No, of course not. What a ridiculous request. I wouldn't be requiring an NDA if that were the case.
I'm really not sure what motivates so many people from the EU to insist upon casting aspersions upon this project and demanding a minute accounting of 30 BTC. Are you considering spending 1500 EUR to fly here and attend the Boot Camp, and that's the reason you are concerned about 3 BTC? Or are you just trolling?
I think you've misunderstood the sentiment about this thread.
It's my belief that there's a feeling you're trying to make a quick buck off the backs of the people you're trying to get to go to your camp.
There's almost no information on what this boot camp is all about.
Are the people going testing your equipment for you? Are you using the results of this test to refine your product which you'll be selling to people? In which case why are people paying you to test your equipment?
This combined with your other thread regarding buying an island makes it look like you're wanting people to just pay for things for you.
Don't get me wrong, if you're running a business, that's great but because there's no clear intention, it's really hard to know where we stand.
Noble efforts to build a community and building a business for yourself are two vastly different goals and it seems like you're building a business under the guise of building a community to me. That's just the impression I get. I might be completely wrong and I'd be happy to be corrected but right now it's not entirely clear what your motives are other than lining your own pockets.
