I suspect the 4 week power down is helping STEEM and LEO over HIVE.

Speed is everything in crypto.

I would go for the model, I think it is TheyCallMeDan that supports it, of an additional instant power down option in return for say a 10% burn penalty.

That would give a double bonus boost to the HIVE economy I believe - more attractive to investors and a good bit of burning.

The security angle on the instant power down option can be dealt with by pre-approval of accounts, and maybe 2FA as well.
