There is no guarantee that the exchange rates are going to hit $30,000 within the next two weeks. In fact we don't know whether the current level can be maintained or not. During the last few days, Bitcoin went up by almost $4,000. Naturally when an asset goes up by this much, profit booking may occur. But in case of Bitcoin, we haven't seen any profit booking till now. It may occur in the next week or by early January.
