Go with BTC man. Majority of your portfolio should hold btc or eth as it has the most growth potential and will most likely give you profits by taking advantage of this current bull market we're having. I'm not saying though that it's bad to hold other coins as I too have other alts that I support. I'm looking at successful IEO's and I'm planning to allocate like 20% of it in my holdings. Just invest smart and always watch the market to know which coins will give you more rewards.
