From my experience, Bitcoin price is always looking up even when most people think it is the end of the hype or whatever they call it. So buying at any price is theoretically profitable on the long term.
it is required to wait and see without using any feeling so things don't get messy when you try to claim what left from the funds once the price dropped considerably.
To resume, I am pro buying whenever possible and regardless of the price. Since Bitcoin number is limited then in the future, it will be more valuable.
