Coinbase one? is it worth it?

Hey there fellas,

I come to you with a dilemma im facing. I hold a good chunk of cryptocurrency and for me, the fees of selling it all combined would be roughly like 300 eur at the minimum.

That's simply to much because im essentially paying for nothing. If I buy coinbase pro or one or whatever its called, will I be able to make the fees smaller? And if so, are there no hidden fees?

If it is impossible to get past these shady practices, what exchange could i refer to to cash out my crypto for low fees?

Some info:

Europe, specifically Lithuania.
