About powering up, be careful because the pumps with hive are extremely aggressive and seem not to last unfortunately. So if we go back to $1 in a few days instead of having a steady uptrend selling becomes a must.
The all time high for steem was in january 2018. That means that the all time high for Hive should be in January 2022, 1 year + a few days.
March 2021 would be the start of the bull run for hive, if it follows past cycles.
