It depends on various factors, such as the individual's skill set, experience, and preferences. Working as an employee for a company specializing in blockchain technology may give the developer access to more resources and a more extensive network. It will provide you with exposure to the latest projects. If you work as a freelancer, you will have the flexibility and financial independence, and based on your contacts and specialization, you may earn more. So if you prioritize resources, work with a company, and if you prioritize freedom, go with freelancing.
