The ability to identify quality coin and profitable coin at that require experience, dedication, skill and love for trading. I believe developing a method is a sure way to know which coin to buy or not to buy.
well, even to buy coins, we have to know what we are doing. buying it without strategy, or just relying on luck will certainly make us disappointed in the future. well, so, I think it needs more than just information to buy a coin.
information about coins is indeed needed and there are many more ways to find good quality coins or not. not only from the ability and experience that is important, before you experience it you must definitely know the weaknesses of the advantages and risks. strategies in trading are very important to avoid losses, so you must determine the strategy.
