I preferred to hold bitcoin and trade the altcoins. Actually I do really have big profit from altcoins rather than bitcoin. Bitcoin is better to be holding rather than trading it because as we can see that bitcoin is still not yet recover from its fell. But it is still depends on you on what are you going to do. But if were you, use bitcoin as an investment to altcoins in order for you to earn huge. I tell you dude, you will have huge profit it alts so dont just focus in bitcoin.
