im invested in internxt yeah, im pretty confident of my buy. CEO comes across really well. not sure if you seen but they just took on a marketting guy to get the word out. CryptoGat and AltcoinBuzz have both done youtube vids on it too. If you have telegram go to their website internxt.io and get the telegram from there, the ceo and admins are really active in there answering any questions.
Obviously any smart trader/investor has a decent stack of BTC in their portfolio. This enables steady growth of your PF, but also allows you to BTFD when they occur and not leaking BTC value when theres a dip.
ETH has a big hill to climb with regards to scaling, but give it a year or two and that will all be rectified and it'll keep hold of its #2 position firmly.
Outside of those two i personally have a few gems that im confident will give me a huge return on a small investment.
Main two of those are Dragonchain (DRGN) and Internxt (INXT). Both low caps (DRGN mini cap, INXT nano cap around $7m), and both have huge upsides.
