I need a better trading platform

I’m just getting back into crypto currency and investing/trading after having interest in it a couple of other times in my life. I still had the Coinbase app on my phone and for the simplicity of getting money onto a platform I threw some money on there to see if I could day/swing trade a bit. I’m quickly learning that I should just buy buy buy right now with the surge of cryptocurrency as I would be up much more.

This isn’t my problem though. I’m recognizing that I’m getting hit with something like 2% fee per transaction and then a spread fee, so I’m not even getting the listed price that I see it being bought/sold at.

TLDR: I need a better trading platform. I’ve heard Kraken and Gemini were good then. A little help for an investor please. Thank you!
