Rather than coming I believe bull run comes, and there won't be any time stamping for the same. From my knowledge a perfect bull run is what we experienced during the year 2017, and we didn't expected much by that time. Those were days of speculation about the year closing price, and to the surprise the growth happened in terms of thousands taking almost every leading cryptocurrencies mark their ath. This time too I never think of the bull run to occur within the predicted timeline, unexpectedly it happens.
Your words are true, from beginning to the end. We don't have time stamp, nobody can't predict the future. I joined right before the
bull run, at the beginning of 2017. I still have bitcoins from that time, my first purchase was around 2000$. I remember that time and you
are right, nobody expected that huge rise.
I believe in next bull run, it will come unexpected, when people stop thinking about it.
