and how to trade bitcoins and earn?
Because i invest bitcoins in yobit.net but i didn't know how to properly trade bitcoins.
On the thing that you asked for on which you need a help on when bitcoins price will go down , definitely no one owuld really help you out because every traders do have this problem and also this thing is a normal thing on trading because no one could really predict on which way bitcoins price will move and thats the thing which hardens the situation. Trading bitcoin is just a basic buy low sell high but there are lots of things to consider . Better to study more before you engage into trading because you would lose money if you dont know what you are doing.
