Trade with one time frame is enough ?

[nicolas1979]

Hai there, I am a day trader. Every trade I made just use one time frame ( 1 hour ). Simple strategy, I need to find 3 top / bottom price and then replace a trendline. If falling down across trendline I choose to sell and otherwise. But in group I join, the senior member says my strategy is really bad. I should take two-time-frame, from one hour ( open position ) into 1 day ( trend ). If I use one time frame in cryptocurrency it will make a lot false signal, that's way I need two time frame. The question is I admitted my strategy is not the best and only get a few $, but opinion from senior member is good to me. Should I change my strategy or not?
