All of these are great, but do any of them accept cryptocurrency as means of investment. Most of these I recognise but I don't think a single one accepts cryptocurrency.
Besides, how do you guys think the best way to do it would be. Have a person set it up and have a goal of 25 bitcoin for example and then have a wallet everything is paid in to and if they reach their goal, pay this to the entrepreneur? Opinions are welcomed!
