All coins mined in 11 days. So most people missed out. A few probably mined the most with their mining farms. Over the last couple months price didn't move much because a small group hold almost all the coin. They do some self buys / sells to make the coin look active and shake out the remaining people that they can.
Now they slowly raise the price so the profit takers can get out. Once that's done it's time to go up again.
People start buying so they don't miss out on the pump.
Then give everyone else a reason to buy and use the coin. That's the big one. Easiest way is to get the drug users that have lost bitcoins due to centralized markets.
Other coins always say, "blah and blah has such and such and we'll just add it." That's good and all but it's the users that keep coming back to buy the coin is what you want. That's why people are buying so many different coins. You buy 10 coins and hope 1 coin makes you a millionaire.
Come on mate, pump coins are designed with some fluff hype and they die out in weeks with no delivery on anything or some copy/paste bullshit. Sdc has been here since july of last year with unique and consistent development and a small and active community.
