trade fear and greed indicator sell above 73, buy below 45

For crypto trading I wonder if you could do well simply trading the coin market cap fear&greed indicator or maybe it along with rsi?? With a little research find the best greed number say 73 and fear I’m thinking low 40’s to buy.
Doing this and. a few minutes a day staying informed about general news reports concerning trends could one do well?
