That's great but there's a bigger risk on only having 2 coins on your portfolio and not at least see BTC and ETH in it. I personally have a combination of 50~70%ish BTC and ETH combine and the remaining is allocated in startup coins that I believe will soon give me profits. Ripple is great as it has a great use case and you can also look in good projects in IEO's. I love startups that have great technology behind it such as augmented reality and great/known people working. We don't wanna get scammed anyways so investing in a well-established project is already great but for startups, you should always stay vigilant.
