BlockFi declaration in Sweden

As I understand it, transfering crypto to BlockFi is equal to lending it out to the company, and the resulting interest is an effect of their lending activities in turn. As stated by the Swedish tax agency (Skatteverket), lending is equal to selling your crypto.

However, as you are also able to trade the crypto you have with BlockFi within the service itself, how are these transactions interpreted by the Swedish tax agency? Is this something you don’t need to report since you essentially lended your crypto out to BlockFi?
