It looks like it may get close to 40k for sure in the next couple weeks.
It looks like you haven't checked the Bitcoin price in the last few hours. The chart is climbing very fast and it has jumped by 8% in the last hours. I think you should correct your statement, as everything indicates that we will have new ATH in a few days, not a few weeks.
It could be because there's still a lot of bullish news surrounding the internet today. One of the most noticeable reason for the pump was the number of addresses holding at least 1,000 btc just reached a new height. So that means the entity and even whales keeps on coming in to the market.
This will basically put Bitcoin into another bullish run, because these whales is the most influential people when it comes to financial and investment platform.
I think the new ATH will be achieved within a few days is almost certain. I wonder how high the price can go .. It is true that the market is very bullish, but I think it is not yet the moment for the new ATH to be set at the level of $50k. I think we'll stay at around $45k for the next 2-3 weeks.
