Trading is simple, when the price is low it is time to buy it
and sell when the price is high.
For newbie these words seems to very simple because newbie thinks that bitcoin trading is very easy. Off course bitcoin trading is easy but you need patience when it come bitcoin trading. Some time the price will be very high you cannot able to buy them, so you need to be very active when comes to trading.
I think this only applies for long term trading. for day trading you don't need to wait for so long time to price increase.
and you can choose other currencies also. few altcoins are very volatile and give a lot of profit to traders. give them a try.
