If we talk about the topic of the thread, then there is a certain logic in his words. The fact is that the level of 18400-18800, which he is talking about, was earlier support that the market formed after the collapse of LUNA. After this support broke, it turned into resistance and now the price will test this mark from the other side (from the side of the bulls). This very often happens when key levels break.
The only thing we do not know is how strong this resistance will be and how strong the position of the bulls will be in December.
So you yourself tried to substantiate the levels that were given by OP. The evidence base of the OP forecast was: "I see it that way", which has nothing to do with market analysis. I will add to your words that the indicated level of 18400-18800 acts as a 61.8% Fibonacci correction level and, accordingly, the price can reach these values.
