Well, I have never really followed these kind of events on Hive, nor participate in it. However, this time I have some Hive on my account, so I am joining to it and powered up 30 HIVE today.
Probably, this is a 1 time event from my side, unless coincidently I will do a power up on the first day of the coming months.
Anyway, I think, it's a nice monthly event and opportunity for those who are hunting some potential, temporary extras on Hive.
