I understand that holding will give you the most parabollic benefits out there but I also enjoy trading a lot, and I think it is necessary to keep every coin alive, I would separate a small or big amount depending on your economy only to trade, while keeping your portfolio intact, this is the best approach I think.
well we will always have a different point of view but at least do it based on your own passion , based on your needs. just remember there always a risk involved. holding have a risk in term of missing the opportunity to but at the dips.
when trading have a risk to lose the profit piece by piece as human nature to want more profit and you become greedy.
