Trading doesn't need big tactics to follow to be successful in the bitcoin. Simply need to buy the bitcoin when price dump and sell it out when it moves to the bigger value. But looking at the present situation buying as much we can would be best option in trading. Adjust your trade value and volume as price moves in the price chart.
But you cannot be sure all the times you are buying at all possible lower prices because market may find further corrections even after you just buy. Same thing may happen when you will be selling at higher prices and right now it is happening to most of the traders. They are losing their potential profits.
I agree we cannot catch exact right buying and selling prices. Losing potential profits is not a big problem for most of the traders but facing losses due to improper buying prices is a very big problems for all the traders.
