Hello elrippo, thanks for reply.
I do not want to put my money in the hands of anyone else, no more.
Starting a company is not a option, for now is just an idea and want to be just a small group...
What's about a non profit organization (good for taxes and with a
real address). 50% for the members/investors (you need a minimum of seven members in germany) and 50% for charity (like SaveTheChildren for example).
Plus some supporters (could be official members, too) from industry (solar-powered mining farm?). Could be a nice idea ... with profit for all
and a good reputation without any scam.
