There are many sites promising to double your Bitcoins in 100 hours or so but do they deliver or are they scams? Here is a list which I will research. A word of caution - none of the sites listed are recommended and they are listed for informational purposes only. None of the content of this article should be treated as an investment advice. Our policy is to invest small amounts in each site and then if the site checks out we reinvest 50% of profits after the initial principal investment is paid back.
