Me i am not good in prediction that is why i am holding long term coin and much trusted coin to lessen ghe risk of my investment. Then i have fund for holding and fund for trading and this is the best way to earn good income specially if you do this regularly.
However, if all you do is follow signals, without having your own brain to use when signal that has been called is going wrong, then it will be hard for you to ever make profit. Some good signals will tell you when to get out anyway. No one can really give a right prediction, but at least some analysis can let you know what can be expected.
