That is no exat idea in trading..suppose if you buy at low price and even after 10 month the price is still at the same rate ..what are you going to do..
That's why wait patiently..just consider 3 r 4 coins and watch them continuously for 10 days, 15 days, 20 days you will get and idea where to buy and where to sell.
This is the best strategy I have read so far. You have to study the coins for a considerable period before lunching into the market. This means you make your own chart of the daily prices.
yeah. doing own study and research regarding the coin price behavior is the most effective strategy, All coins can be profitable even shit coins, Just know when to buy and sell them
and can have some profit even small. Always keep patience in trading for best result
