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.
