To earn in bitcoin,hard work is needed.It is not gambling to fully rely on luck.Bitcoin is not a quick rich scheme.
Even in trading,you should do market analysis,read price charts before doing any trade.Otherwise,trade would end in a loss.You should not be emotional and should not do panic selling.
If you believe that you lack such trading skills,then you could buy ASIC miners and start mining bitcoins.But cheap electricity should be available to get more profits.
