I think its better to hold your bitcoin for the meantime instead of selling it. As we all know that the bitcoin is getting more popular and its value is getting more bigger. Then sell it if it is already in greater value, so you can profit money.
yes I will also agree with you, that holding bitcoin will be more profitable, although no one know about the price of bitcoin that either it will increase or decrease. but still from the current situation and the people prediction we can come to the conclusion that holding bitcoin in the present time will be more profitable, because most of the people are expecting that the price of bitcoin is going to increase more, and therefore most of the people are not selling their bitcoins.
