Holding for an year is is not a good play in my view.....any coin with a desirable team is worth considering but rotation at least for weeks is very important since this is the only year for the birth of some interesting coins which can change our future....once every coin gets stabilized,we cant expect miracles....so at least for this year,its better to trade on weekly basis...
I think different things work for different people. I am never a big fan of trading. simply because i do know my limitation. However if it works for you and as long as more money is getting into your portfolio bravo. I am a big fan of finding a good project and hodling.
