i wouldn't invest in anything if i were you, and instead i would put that money in a bank account (hold the fiat instead) because if i am so unfamiliar with a market that i had to ask random people on the internet for random suggestions aka investment advice then i would prefer holding the money i have instead of throwing it away in a gambling manner.
not to mention that i believe that "investing" in altcoins is a very bad idea, you must be a short term trader when it comes to altcoins.
