Could you explain what really happens on halving. How one gets profit on this day. How the BTC is used on this day to see more profit. Whom should be approached to do so?
It is not guaranteed that you will get profit immediately at the halving day because nobody knows what will happen exactly. Mostly who will be affected are the miners because their earnings will be cut in half.
yes and we cannot predict that everything will go fine at the time of halving, its full of surprises, it may go higher or lower, best option is to sell coins when we see higher price instead of holding it too long.
