Don't make a decision quickly, you might change your mind 2 weeks in. Give it a month or so, if you're sure about it then make a decision.
In the end it's the question whether you like the status of the account or the fact that you can use it for certain activities. I mean, if you level it up, what are you going to use it for? Do you think those activities will warrant leveling the account? On the other hand, simply having the account and never using it is a waste. It's all priorities in the end, but make sure you think the benefits outweigh the cost of losing your account by a great lot before making a decision.
