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?

Loss 50% of your portfolio is a common situation here, in cryptomarket.
My loss is 3.2x from peak in January. I like these positions in your portfolio: ICX, Dragonchain, UTrust.
You're not alone brother because the market was really down since the year started and many had cut their loss even they know they shouldn't be doing that. OP shouldn't be expecting an instant profit here unless he do day trading but when he just hold he should have more patience to see some decent profit.
