That is certainly one of the possibilities. We cannot know for sure unless the OP gives us more info.
Purely out of curiosity, I looked for mining and trading website templates on Codecanyon, and you are right, there are tons of ready-made website templates on that topic. It is possible that the OP bought one of those websites and does not know what to do with it. But in that case, it would be better for him to seek the support of the developer for some concrete information and support.
Creating and launching a trading platform is not an easy task at all, and it cannot be implemented by a single person, even if he has the necessary budget. The strange thing is that the op came to ask about licenses, bypassing all other stages.
