SAFE is centalized exchange (for now) and they are in early early beta. What I like is that at least they have some working product (just few coins listed for now, but their exchange exist like 1 week or so). If we look top 30 coins, I guess 25 of them doesn't have anything except whitepaper and nice wishes for the future... and their market cap is in billions. SAFE total supply is only 36 milions and if they manage to deliver good product, it could give 30-50x profit easily!
