I went all in 2017 and literally have no plan but to wait it out. The truth is that altcoins are almost half or more in my portfolio. I actually regret not getting more bitcoin and ethereum because they are part of any good portfolio. I would like to extract some value in 2018 and leave the rest be.

The fact that you mention that Ethereum doesn't seem like an altcoin. This is interesting because I too feel the same way. ETH is up there with Bitcoin and it is the rest from the coins that seem like altcoins
