Even if it took us a lot of time, we have learned our lesson, I still remember the predictions back in 2017 that said that bitcoin could reach one million dollars in a matter of months, and many investors actually believed those numbers were possible.
Now we know that such a price is still very far away, and even if 400k is a goalpost that it is easier to reach, at the same time it is a price that seems to still be out of reach, and at best I would expect to see that price until 2029.
Now the price has not reach to the value of 100k$ and people are asking about 400k$ that will it be attainable or not. First of all we have to wait and take benefit when price reach to 100k$ and after that we will increase our target to wait for 200k$.
I think its not an easy thing that bitcoin will suddenly turn 400k$ from 70k$ and it can only be possible when market never goes down and continuesly upward movement take place but this can only be a dream not reality.
We should keep calm because everything can happen but time is needed for it and I think there will numerous years required for getting such value.
