WHAT DO YOU THINK ? 
The more you wait, the more opportunity you'll lose. When you posted this thread, the price of Bitcoin is only around 5000 USD, and now, Bitcoin is at 6300+ USD. Think about how much you should've earned by now. You've wasted the opportunity to buy at a lower price. So will you wait another second hoping for Bitcoin to go down? Well, we cannot be certain whether Bitcoin will have a correction sooner or later. Regardless, it should be a lesson to you what you've wasted.
