I have currently traded all my Bitcoin for altcoin. I believe alts will pump much more than Bitcoin so I plan on riding them up to gain Satoshi value and then jump over to Bitcoin at the peak.
It was fine to trade bitcoins with altcoins as long as you have the assurance to earn profit and that is the reason you have to look at the platform before invest a huge amount into a certain coin.
Altcoins can bring you very good profits in a short time. But there are also quite high risks. Therefore, I choose bitcoin, because I prefer stability
