You have to buy what people want, before they know that they want it 
+1 thats what ryans saying here http://pumperspicks.com/game-win/ if you don't have what people want, then you cant sell anything. If you cant sell anything, then you cant profit
Back in january no one wanted these coins but i guess thats why people profit when they do the opposite of whatever the herd is doing
You don't need to "do the opposite" because "the opposite" may not actually be the right thing to do either
What you actually need to do is understand what "the herd" likes to buy and why. then you make sure you buy all of that shit BEFORE they do and at the lowest price and then stack your shelves sky high
