I am also an altcoin lover and my top picks are eth, ltc, eos, neo, ada and icx but i would recommend Eth to hold because great upgrades are coming and i expect massive rallies for eth towards the end of the year.
from what I see ETH is still an altcoin that is liked by many people and indeed that is not surprising because ETH is still the king of Altcoin so there are still many people who like and believe it.
what is certain is that altcoin is diverse so there are certainly many altcoins that are potentially good in the future.
