 Considerations:
 Tricky HYIP, design is really cool and attractive, but basically it's just a short term HYIP, probably very short. Be careful. People can login in other accounts and withdraw instead of the owner, what they need is just the BTC address.

 Considerations:
 Hourly HYIP, actually in early stage, can be profitable for early investors. Probably just for one cycle.
