I probably go to ethereum, it is my favorite. Everybody loves it because it is a good thing when it becomes to investment, I also saw a lot of potential in them like what everyone saw on them. I have a lot of eth still holding them in my wallet hoping to have a bigger profit. Eth is the only altcoins I'm holding till now. Because I know that they will grow like what happened to bitcoins. Not as expensive as bitcoins but they can be successful like what bitcoins have achieved before.
