Easiest way for a newbie is to pick 10-20 coins with potential that are really low and invest in them, hold, some will go xxx% eventually.
Even not those in top, sometime some new launched token were capable also on pumping, If a newbie really wants to start trading then better collect more potential alts its better to have such new coins too since there are more ideas and planned development for it,hold till it fully developed and see how it pumps.
