i am not thinking that price will reach 4000$ but i think i will reach atleast 2000$ . since no one can accurately say that what price will be but in my openion the price will be above of 2000$.
4000 dollars will definitely be reached in like 2 years or so, bitcoin is going to grow at a very rapid pace because of a really fast adoption
i think two year is very short time for bitcoin price reach to 4000$ , i think it will take too long time like 4 or 5 years that bitcoin price will be reach to 4000$ because bitcoin recent price is 565$.
Yeah don't expect $4k price before next 5 years as its never gonna happen and we all know that how long its taking even to touch the price of $1k and I think it will not even touch this price in next halving in 2020.
