Interesting $4000 just 2 coins, here I’m just a newbie but I think ETH is number one here, I think this coin very stable when growing up or correction. Then the second is select the cheap coin that you believe can to the moon sopn. So, you can earn a lot with that, of course crypto has a high risk for investment so prepare your self if you can lose your money. My suggestion you can check ETC, LTC, NEO, WAVES, XRP, XLM. Do research for that coins so you can choose which is better for your investment.
