I did get a couple filled at 303 hive a few days ago. There is a decent bit of action in the market if you let them ride a few days. Even though that was a drastic drop when there were about 20 sales in a row.

It seemed like it was being factored in as is, but I'll ship it over if not.
I have a couple of plots sitting for sale that don't show up for SPS but if they are just in the wallet then it looks like you are ok. Mine don't show up for the airdrop but it's obvious when they do as they are 10k points each.

It's just my personal strategy at the moment to keep buying DEC and holding as there are a lot of airdrop points for it and then use the SPS to buy more SPs. I will sell it all at near the end as prices will probably drop when the airdrop is over.

But i do think that it is fairly tied to the price of SPs and will rise if SPS rises.
