Yes, I even suggest to many of my friends, trading is always better because in some exchanges you can find there are some huge volumes of the reputed coin. So before entering into trading find the best one which will give fruitful income for you in the long run.
But you also have to remember that their are risk in trading as well. Its not just finding the best alt-coins out there to invest, but you have to know when the big pump or dump is coming. So if your friends are new to trading, they will have a hard time at the beginning and might give up if they see that they are not profiting as they want to be.
