Which broker is best for trading cryptocurrencies?

Choosing the best broker for trading cryptocurrencies can be a daunting task, especially with the vast array of options available. One must consider factors such as fees, security, available cryptocurrencies, and trading platforms. For instance, some brokers may offer low trading fees but have limited options for cryptocurrencies, while others may provide a wide range of digital assets but charge higher fees. Additionally, it's important to evaluate the security measures implemented by the broker to protect your assets from potential hacks or thefts. It's also crucial to check if the broker is regulated and licensed in your jurisdiction, as this can provide an additional layer of protection and transparency. Given these considerations, can you suggest some brokers that you believe are well-suited for trading cryptocurrencies, and what specific factors make them stand out?
