TIP: NEVER Invest in a site that is built only to offer the "investment opportunity" or "game" because they always end the same way...with the owner taking off with the member's money at some point and then they make a new site, with an even better name, look and offer.
It's a bad idea to "invest" or "play" with any ponzi offer because they only hurt the crypto community in the end. Because every time a ponzi goes down, some of the people leave all crypto coins and NEVER come back. They blame the coin or the technology and they will never trust the idea again.
Your better off trying to "gamble" with a cloud mining site at least some of them are actually mining the coin (helping the network and community)
Obviously I disagree with this, but let me give you a little explanation why.
A "cloud mining site" that takes in your money, and then gives you back a little bit each day (which really is what most of them do - they don't mine - if you really pay attention they look the exact same as a ponzi game [go compare EMICoin.com and EarnTomorrow.com, they're the same site with a different front end]). We are perfectly honest up front. Our wallet for this site currently consists of exactly 0.010149 (as stated in the statistic part of the site). We immediately pay out our users to ensure that we cannot run away with people's money.
In general, I agree with the honesty in the ponzi space. However, this is pretty much guaranteed to pay people back as long as new people keep coming (and if they don't, you lose the game - kind of how any ponzi [or cloud mining, if you're that naive] site works).
Sites like this support economic growth and redistribution. If you're looking for a more long-term site, something like
http://CryptoPyramid.com is something to look at. It focusses on random distribution. If you're looking for a comparison of investment opportunities, I sumbled across this one here:
