I believe after the $10k milestones will have reached by the bitcoin and some people will be ready to cash out from the bitcoin and take out all of their profit and try to buy back again later.
As per the massive adoption still continue and that gives the fundamental reason to pump the bitcoin right now, it's really difficult to determine when that will be happening.
EVerybody says it will crash hard, but there is indication for this so far. The trend is still strong in the market and buyers are keep buying bitcoin. We can see $11k-12k like prices if the trend maintains by bitcoin whales.
