Its normal nothing really to worry about. If you are planning to buy this would be the perfect time, each time it drops buy little and little. The reason is very obvious people are confused and sacred of August 1st.they just don't know what's going to happen and they are running here and there and selling it in panic, that has led to more supply than demand and that's why the fall. Till august 1st the fall will continue, then Boom Boom rise.
