Best platform to trade BTC in Europe / France

Hello,

Been holding since 2017 and I'm wondering which platform should I use if I wanna transfer some BTC from my cold wallet to a crypto exchange platform.

I'm from France. I would like to know which platform has the lowest fee when just transferring from time to time. Not trading every day / month.

I'd like to withdraw a little bit and re invest later when it will go down. If it goes down again. I was on Coinbase but coinbase pro is not working anymore. And I'm not sure the normal coinbase site is good enough. I mean it's secure but if the fees are too high, maybe there is a better option.

Thx for your help.
