That's a fine way to look at it...keep doing that if that's what works for you. BTC is the onramp to the rest of the space for sure...However, once you've made an obscene amount of wealth in BTC, then it becomes logical to diversify. Coin ICO's are a way for normal people to participate in a space that was previously off-limits to normal people..venture funding. I find that VERY exciting, because I've been an investor and trader my whole life and have never been able to do venture capital. Yes many ICO's will fail....just like in any VC deal. But there are some very interesting projects out there, and it's great to be able to participate in them.
