What would it be advisable for me to purchase for $ 8,500?

With $8,500, I wouldn't even suggest that you look at just investing in a single coin. I think that you should be looking at investing in a couple of cryptocurrencies. For one, I would suggest that you invest a reasonable part of the funds in Bitcoin, and then share the other part into whatever you chose, and invest in some good altcoins.
