If I won 10 SBD, I would convert the SBD into Steem and purchase 5 shares of @steembasicincome for the first 5 members who joined a community I started called @BirthdayBoost. I would give this away as a small thank you" for their support.
I would use would use the remainder of the SBD to promote the community of power up.
I am looking for opportunities that have an immediate impact and will keep giving in the future.
Thank you for your detailed comment @sumatranate on how you would use the 10 SBD.
