The social network X, owned by Elon Musk, has launched a new feature — the ability to give tips in $BTC through integration with BitBit and Spark. This option allows users worldwide to instantly exchange bitcoins, supporting Musk's idea of creating a 'universal app'. The feature operates on a self-management principle: tips sent can be collected within 21 days; otherwise, they are automatically returned to the sender. This has become another step towards realizing Musk's ambitious vision of combining social media, financial operations, and artificial intelligence into a single platform X.
