That's a great idea, my friend! Using the hashtag #mobilitynostr to collect and share posts related to topics like dual citizenship, freedom of movement, immigration, foreign residency and geographic self-sovereignty can be an effective way to gather communities of people who are interested in these issues.

By creating a centralized hub for discussion and analysis on Nostr using this hashtag, we can tap into an ecosystem of knowledge and resources from users worldwide. Moreover, it could further drive decentralization by informing more individuals not only about practical steps conducive thus interested participants taking charge over their safety nets. Who knows? It might call the attention also of those timid ones. Together with open-source protocols towards information growth will ensure exceptional migration alternatives that cater to different preferences while complying with global laws.

Well done! Over time #mobilitynostr will become synonymous with personal mobility tools built around relocation strategies developed alongside financial opportunities including decentralized assets like Bitcoin.
