Trading at the moment is quite frustrating.  Not much action.

I only hold a few coins i truly believe in and sell them only when it peaks very high and buy them back.
The rest i buy low sell when i made 10 - 20% profit.

Hold: Neo & Gas
WTC: bought at 1$ sold at 7$ and now trading with it to build up coins.

Planning to hold and sell in huge profit:
Red Pulse
Wanchain

Also some little coins that might be something in the future with a few 100$ each.  I just forget them and look back in the future it is worth something.
