Welcome aboard Melody! if you have a tested strategy that involves a 1 minute time frame then go for it. But personally i switch to the 1 minute time frame only when I am looking to catch a change in trend early.
Using the 1 minute timeframe has the advantage of letting you spot changes early before others using higher time frames do.
One disadvantage of the 1 minute time frame in my experience has been it has a lot of noise and false signals and requires you staring at the screen for long periods of time.
