Coinbase's trading fees are LITERAL ROBBERY!

I wanted to share my experience using coinbase to trade crypto, so others won't fall into the same trap that I did. I started a coinbase account 3 months, ago, but hadn't used it. Recently, I used it to sell about 10k worth of crypto that I was hoping to swing trade. Coinbase charged me $180 DOLLARS TO SELL OUT OF 10k WORTH OF CRYPTO! Then I decided to buy back into that same coin after waiting a bit, and coinbase charged me $150 to buy back in......... In other words, Coinbase charged me $330 for a sell/buy round trip of 10k worth of crypto..... I'm absolutely blown away and disgusted by their trading fees.

After this experience, I want nothing to do with Coinbase anymore. Does anyone know of an exchange that does prison shower ****** you when you are trying to swing trade crypto? And if not, what is the best way to swing trade crypto without losing and arm and a leg???
