Hi. I had lots of Hive on exchanges until recently. As you can see I powered up to set an example.
It is probably not wise to power up from a risk reward perspective, but I think it is important that we power up if we are going to persuade others to do the same (congruence etc.). I think we should focus on reducing the power-down time significantly. I think the long time, given the volatility and the Nature of the crypto markets, scare people from powering up.
RE: If you could write a letter to HIVE owners on exchanges, what would you say?
