I think bitcoin won't fall at 2k even though the market is very bad this year, 2018 is almost over and will enter 2019 and bitcoin will open a new sheet and be more likely to recover.
No one can say what will happen in the coming future and moreover bitcoin's value is very volatile and it depends on a number of factors.How much investment is done in bitcoin determines its price.The forces of demand and supply also play an important role.If bitcoin is being banned in any nation then also it will affect the price.But I do not think that it will go lower than 2k.It has a lot of followers which support it every time as it gives them good profits.
But look at the price now, it hasn't move down yet. So, that means it has a higher chance that the price will go up or stay at this rate. Anyway, let's not rush the bull market to come since there are most important ones that would have to start first. And yet, ETF hasn't been accepted yet by SEC. I wonder what would happen to the market if ETF gets approval.
I don't think because the price of BTC in the market is above $3800 and it went upto $4200 last week this shows the positive affect on the value. So it is difficult for BTC to go lower than $2000. BTC has dominance of 52% over all the coins hence hoping for the best to come again for BTC.
