I think you should start with asking how much of this $5000 are you okay to lose. Cryptocurrencies is still highly volatile and risky compared to other traditional assets. So if your answer is this $5000 means a lot to you, and there is a good chance that you will need this sum of money in the next 5 years, then I rather you not invest in crypto.
If you are at the other end of the spectrum, and think that you can afford to lose this $5000. Then we can talk.
Personally I have a very high risk portfolio at this point in time. Why? Because crypto market just crashed from its ATH and is still in a bear market. Like any other markets, the small caps have the largest room for growth when a bull market starts. That is why I am a firm believer of scooping small caps during bear market and progressively sell them for large caps during bull runs.
That being said, I still keep wide portfolio of cryptocurrencies. My largest holdings now is actually STEEM and ETH (about 10% of my portfolio). Then I have multiple small caps that I think are promising, all in rather small proportion. My personal favorite are SUB, PRL, NEO, AION, ICX, BLZ, REM, ADA, TOMO, HKN, ESS, MFT and GO.
