In conjunction with other elements, consistency can be very powerful. The key? Never by itself, I believe.
Anyway, I’m glad I powered up today and most times, I don’t always wait till HPUD day before I do so.
That was my strategy too, in the beginning, to powerup whenever I had some HIVE. I didn't even understand why others give so much importance to HPUD. In time, I got convinced as well. HPUD serves as inspiration/motivation to others, and it is easy to plan for, without taking the price variation in consideration.
