The best place to find potential users of bitshares is in bitcointalk, because they know how crypto system works.
Why not give all users of bitcointalk a generous amount of free bts.
1. Make a snapshot of all bitcointalk users and their ranks.
2. The amount of bts to receive is different from their rank.
3. Then they can redeem their free bts by going to site like
http://bitcointalk_users_get_your_free_bts.com/<username>
4. Requirement is they need to use account name to redeem, this way we know they have the bts wallet.
5. to check if they are the actual user they need to add a required signature in bitcointalk forum like "Get your free bts here" and the link is their referral url (
http://bitcointalk_users_get_your_free_bts.com/<username>)
6. If someone clicked their signature then they get a 100% of this user claimed bts, so they will keep their signature.
