If You want to Maximize Your Profit In Trading Then Follow the Below Steps:-
1) Firstly Choose a Reputable And Legit Trading Site Like Yobit.net Or Poloniex.com
2) Then Choose Some Reputable Coins and Then Check the Supply and Demand and Past Price Fluctuations Of the Coins You Choose.....
3) Then Just Invest Your Money in Them and Wait For Sometime and You Will Get Profits.....
Also I Suggest You that Don't Invest More tham If You Can't Afford To Lose.....
Your second step is the biggest challenge for any trader. Unfortunately the reputed altcoins are not giving rooms to better trading with its fluctuations. Yes, reputed coins are stable with its price levels.
But, as per your third step if a trader will be ready to wait for longer duration, then trading with established coins must be the right choice as those coins will give definite profits to the long term holders.
