Seems like a decent idea to me.
As far as demand goes, it's likely neutral though could be positive if the steem earned isn't immediately sold, even then, it may help introduce steem to more people, which is a positive.
Seems like it's worth a try to me.
Hi @jrcornel,
Thank you very much for your comment and your encouraging words. It's true that some users might exchange the steem back into fiat but even if only a small percentage keeps the money in steem it would be a plus.
I imagine also to create a fund with a percentage of the revenue as a kind of saveguard against insolvency of networks. This fund would be kept 100% in steem. Like that I could guarantee that at least this percentage of the revenue would remain in steem.
Best regards,
Achim
