It is possible that Bitcoin price reach $250k, but it will soon after that drop under $100k. Also I would speculate that more possible time frame is 24 months and not 12-18.
The same pattern as it did with its past all time highs. $250k is such a huge amount to think of and IIRC, there's one famous crypto guy that has predicted this, Tim Draper.

2017 Bullrun had made this person become famous as he perfectly projected it but I don't think he gonna be right again this time. $250k is really high and never in mind to think we can reach it, maybe $50k is close to reality than this. However, it was him to project and give his optimistic speculation (and I believe we all that the same) and it's up to us to draw any conclusions as anyone can make their opinion as well. But just to say that it looks impossible and never have to expect for it.
Let's give him the credits if he actually made it last time but this time, a lot of doubts and they are not pushing us to believe them that the price will go exactly as $250k. I'm part of those people that are waiting for the all time high and if it suddenly appears, I'm glad to see that but if it didn't, that's what I'm expecting. But the given timeframe of Tim is longer than what @OP is predicting, it's earlier. This is a waiting game.
all obviously want and hope that the price of bitcoin can be $ 250K, but now we also have to be realistic to see the reality, is it possible to be achieved and achieved by bitcoin?
This is a separate question in dealing with matters relating to the rise of bitcoin which is fantastic.
If you look at halving the past both first and second, I am very sure that there will be an increase in bitcoin in the year after halving. if the third halving is this year, it will be certain that there will be a change in 2021, but in what month will the highest price occur !! once again the first and second halving occurs in December, will the year 2021 also occur in December?
if at the end of 2020 bitcoin could reach $ 15K, there might be a surprise at the price of bitcoin.
bitcoin is currently maintained well in the $ 9K range, a good sign, of course. we are just waiting for the next few months with bitcoin, hopefully that hope can be realized even if it is not as high as expected, the important thing is more than 2017.
