5000$ is a lot of money, but keep in mind the biggest gains with most of the popular currencies have already happend (ETH, LTC etc.) so if you invest now your chance of a huge return like you would have received if you had bought ETH early this year is a lot less likely to happen then back when those currencies were "undervalued", if you now buy in you won´t have the same leverage since the increases in price are still huge compared to classic investments but the chance for 200-400% growth seems smaller with established coins right now. (personal opinion, not the majority opinion). Also keep in mind if the price goes down just after you have bought you will loose a sizable share of your 5000$ on paper (if you dont panic sell since those 5000$ are closer to your heart than you initially thought).
The Other option is investing in ICOs, like with every investment you should stick to grandmas words "never lay all your eggs in one basket".
Research 4-5 ICOs, and i mean really research them, think about their business case, about their real world competition ( most regular people don´t know what the blockchain is, even less so do they know they need it in their life as a customer) and then invest into your top list.
If you do that, you will become a pint-sized venture capitalist, sounds good right?
Just keep in mind you will invest heavily in the founders and their idea of a mainly not yet finished product - this can be the best thing ever (think microsoft,google,amazon,facebook) but i could also be a complete loss like that DVD+ player you bought instead of a Blue-ray player (if you don´t get that reference it is a clear sign i am to old).
With Trading you will have to invest a lot of time constantly, otherwise you will rely on stop loss&take profit orders which could ruin you if you don´t watch them carefully (google gdax ETH flash crash for further reading) and with ICOs you have to take a leap of faith into the founders and them chasing their dream, partly with your money.
I would prefer you invest into ICOs, but maybe because I am part of an upcoming ICO myself, so take that with a grain of salt.
