For me, if I dont really need money I will not going to sell, I want to double or triple my money. My plan is to hold for a long time hopes that many people invest in bitcoin, many will use it so that the demand for it will going to increase and so the value will increase too. I'm just going sell if I really need money like in emergency cases only(cross finger). Hopes that nothing bad happens. And when I'm going to invest in something good like mining rig that we all know that is expensive.
Don't worry to hold bitcoin for a long time, many of people is supporting of bitcoins and bitcoin is great investment too
better to buy bitcoin than buy the tools mining. I guess.
