Yes I think it were 150 stakes that were to be auctioned. We're still planning on doing something like that but personally I'd like to see how many unclaimed stakes we have first.
Also we'd like to not only sell more stakes we want to get more and new people in. Maybe we can somewhow use the stakes to attract some of the miners (not by letting them mine for the stakes but by converting them).
Maybe we can use them to attract some completely non-crypto people via giveaways.
Could also use them to found 3rd party projects that'll aid the ecosystem.

Many possibilites but it'll prob be easier to decide once we have a number.
