This site is ponzi hyip scheme. There are already more two of this kind of site using the same design and system, one of them already turned into a scam. They offer some satoshi rewards for free, but the real attractive of the site are the investiment packs, which you need to pay 0.5 BTC to earn 1.25 BTC after 16 days. Total ponzi scheme.
Yeah i saw many site out there the same design and yeah almost all same as scam.. better to stay away and i hope moderators can lock this thread or move to trash so that no bitcoin users will bait again..
