Yesterday I posted about this site. I have just seen another 0.002 come into my account. I deposited 0.001 Bitcoin and I now have two in my account. Since I want to make sure I do not lose money, I have now kept my original 0.001 and deposited the profit. After 100 hours, I will keep another 0.001 just to be happy that I made a profit and re-invest the rest until I get 0.1 Bitcoin. Nice strategy? Do not be greedy and put big deposits. Rather spread then around on other sites in small quantities.
