if you are so new that you have to ask this questions from random people on the internet then it is not the best idea for you to invest in altcoins! because you seem unfamiliar with this market and because of that your chances of loss are huge.

instead try to stick to smaller investment and bitcoin only and then slowly watch the altcoins and decide for yourself which coin to invest in after you saw at least 20 of them rise up and crash hard after they pumps were done. so that you know what you are dealing with here.
