Invested beginning January 10th which is now over a month
HODLING the following alt coins which I believe are all great projects:
-ICX
-Dragonchain
-WaBi
-Enigma
-Sub
-Enjin Coin
-POE
-bounty0x
-UTrust
-Medibloc
-Linda
And portfolio is still stuck in 50%. I thought things will get better in February but still not able to see any green.

What can I do? Making me want to give up and sell. I don't know how long more to wait from here. Will I see any light?

Only a month, and your patience is already at the edge of the line? You will not gain anything if you continue to be like that. Forget your portfolio. Get your thoughts into something else, do some bounty campaigns. I'd say in 5 months time, you will see green butterflies swirling around your head and pocket...
