My father is anxious pertaining to the fall and rise in bitcoin price. He has four(4) btc and he is afraid to hodl. He wants to sell at a lower rate. Any advice for him?
I think in every speculation there is a risk, and if bitcoin grows back it will be a regret for your father.
once again this is a matter of experience, knowledge and searching for all sources of information to ascertain the stage of speculation decisions.
