You are actually holding a good amount of bitcoin now,so even with a slight increase in bitcoin prise you could achieve some good profit with it.So i would rather advice you to just hold onto them until bitcoin reaches even more heights.Its the safest investment according to me for you.
I think some of them should be invested in trading and rest should be saved for the future, as if you are lucky enough then you can make some good profits from trading.
you are right, thats why i do trading in order to make some money over time, i hope that it will make me rich in the future
