You mentioned here that you are a small investor. If you plan to invest as a small investor then I will tell you to invest here the amount of money you can afford to lose. So I would not tell you to go with high risk coins to invest first I would tell you to always invest with top coins and move on. Although investing is risky, if you can go ahead with the top coins, I think you can be pretty much risk free with your investment. So I suggest you to invest in bitcoin and ethereum if you can buy and invest in these top coins then your investment will be fruitful and you will get returns from here. But never risk investing by buying shitcoins, and some worthless coins.
