What are the best low-cost crypto exchanges?

I'm interested in exploring the realm of cryptocurrency investments, but I'm on a tight budget. Given this constraint, I'm wondering: What are the best low-cost crypto exchanges out there? I'm looking for platforms that offer competitive trading fees, minimal deposit requirements, and a user-friendly interface. Additionally, I'd appreciate any insights into their security measures, supported cryptocurrencies, and overall customer support. I understand that balancing all these factors is challenging, but I'm hoping to find a reliable exchange that won't break the bank. Any recommendations or personal experiences would be greatly appreciated.
