I like the idea of burning some, while airdropping the rest on SP holders.
Have the Steemit account delegate the airdrop. Instead of the tokens dropping in all at once, have it trickle in over time at a steady rate. That could at least stall people from running to the exchanges in the short term. SP holders can then still take advantage; when curating, for example. The current dolphins would then be able to support many more new minnows so even those who benefit the least from the airdrop can still be rewarded.
I don't like the idea of dropping it on the so-called "best". Even though I've done quite well here, I'm sure even someone like me would be excluded from the list of best dressed.
I'd recommend the top tier whales receive a smaller percentage than the middle tier dolphins. Not because I'm a dolphin and feel like being rich, but because we have enough problems with power being in too few hands. Spreading more around in the middle would help resolve that issue as well. I bring that up because I heard STEEM was recently rated a B+ by some group who grades cryptocurrencies and the only thing really holding us back was the concentration of wealth at the top. Even though I'm suggesting they get a smaller portion, they'd still see the greatest gains once the entire picture becomes clear; as in, STEEM mooning.
Have a nice day.
