my advice will be to wait a bit. I guess the price will go down in December and then go and buy it

Its a wild guess. I don't feel of having a huge dump by December, instead we hope it will continue increase and reach for $7k maybe. Not only the price today is the basis of having investment but we must consider also a possible to happen in the future. Even though bitcoin price is very expensive but still is an earning investment. We should not be worry of having dump because that is bitcoin really is and it will back again.
