I had $10k in a high yield savings account. At first, it was earning about $20 a month in interest, but now it only earns $3 or $4 a month. Did I make a better decision, equal, or worse decision?

I got tired of looking at it doing much of nothing so I opened a Fidelity Go account. I know this is for beginners, which I am. Is it a better decision to have my money there instead of the savings.... more room for growth, etc.?
Again I’m a beginner, so I’m making beginner moves.
