It only takes about 2 minutes of reading to learn it is not even a tiny bit of a scam.  But most people here don't bother with research - they'd rather look at the pretty meme.  Widespread stupidity is the best friend of most of these altcoins.  A total inability to read and understand a project propels the dumbest coins the highest.

MaidSafe is a brilliant proposal with loads of effort behind it.  Whether or not they can get it going will be interesting, but it has potential.  My recommendation: buy.  But, this is a long term deal.  This is no high flying 'Blackcoin' going to the moon.  It will take about three years before you can become a billionaire on this system.
