Best Exchange for Long-Term BTC DCA?

Hello,

I’m currently buying BTC using a DCA strategy (500€/month) and plan to hold for the long term. Right now, I’m using Kraken because of its good customer service and ease of use.

However, I’m wondering if I should switch to lower fees. I’ve seen many people mention Kraken Pro, but I don’t really see the difference compared to the regular Kraken version.

My questions are:

• With my strategy (500€/month, buying and holding long-term), is it worth switching to another exchange?
• If I switch, will I actually find a cheaper exchange?
• Any recommendations for better platforms in terms of fees and security?

Thanks in advance!
