No one has obviously seen $72k, we are in unchartered territory now, bitcoin has surpassed $58k already and we have set a new all time high. And we are going close to $60k-$70k this month. So I doubt that we will see $40k now specially if this bullish trend continues.
So again, those predictions are going slowly into reality, and the best thing to do is to just HODL and wait for the imminent $100k this year.
Nobody has seen 20k before neither, but 2017 allowed that, hell we weren't even at 10k before 2017 and we have seen that, this year allowed us to see 30k as well, and 40k too, and 50k recently and now we have seen 61k as well. This means there is nothing that could stop us from seeing 60k neither, that is going to happen for sure, there is nothing wrong with bitcoin reaching those levels, we have always broken one all time high and reached another all time high, that is how bitcoin grows and 72k will be the next one.
People could argue about what bitcoin will be and how high or low it will be but I can guarantee you that bitcoin will see 72k one day, it could be this coming week, it could be 2023 but it will one day happen, this is why I am not getting out, I believe 72k is possible, I believe 100k is possible and I honestly think that 500k is possible as well.
