this is a naive view of trading strategy, or the common mans trading strategy. the wise man buys dips and holds always, because the value of the commodity will increase according to inflation, thus maintaining and even growing in value relative to the investment. if i am gaining interest on 2,000 in the bank, my money loses value due to inflation. but if i place 2,000 in a strong stock or crypto, in a year it may be worth $2,400 , maintaining its purchasing power despite inflation, and thus the real value of my investment is maintained.
