Everybody have their own choices of looking for money both in crypto currency and in bitcoin,some persons prefer holding while some person's like to trade daily,it all depends on your choice as an individual,and what you want to do,but the reason so many person's like holding is simply because it has no risk involved,and all it's needed is one being able to exercise patience.I love holding my coin but at the same time there are sometimes when one needs to just act fast if he sees that the market will be favourable,that is what puts me in trading,I trade when I have calculated the risk involved,and I make sure I trade when I won't loose,but make profits.
