If we will take a look at the chart and on the 2nd halving part. After the 2nd block halving there you see a new all-time-high.
So, for me, probably like months after the block halving we can able to see a new all-time-high, like probably as what others said: The year 2021 is when the Bitcoin is probably getting its new all-time-high.
Please take into account the competition. Bitcoin cannot and will never offer privacy. The people of this world demand freedom. And you can't have freedom without privacy.
Therefore, Bitcoin will become obsolete as other better and newer models out maneuver this dinosauric tank.
