If is your plan for a long time investment with your $1000 though to me the amount is not much, but I will advise that you should buy one or two coins like Bitcoin and Etha then hold for a period of time and I do hope you will gain profit any time you decide to liquidate your investment. But you most have in mind your profit percentage and once you hit, there is no need to wait just cash out and wait for another opportunity to reinvest your capital.
Op had chosen to start a small amount, but I don't think buying several types of coins will be profitable in a fast ways. It needs the be funded with huge amount but for a newbie starter $1k for him was just enough to accommodate as good entry point. As a suggestion focusing with btc is an assurance for us to gain an exact amount before thinking for another coins. Using your passive income will also be a good for diversion on altcoins that has good potential in order to expand you holdings capabilities.
