[Ivan Kaleja @ivan_kaleja]

Financial freedom was never a choice until Bitcoin! Congratulations @BitcoinFamba for all the work you are doing!

[Bitcoin Famba 🇲🇿 @BitcoinFamba]

Anita @anitaonl emphasized:
Bitcoin’s value is not only in holding.
👉 Its real value comes from being a medium of exchange.
Use it. Circulate it. Build with it.

[Ivan Kaleja @ivan_kaleja]

Bitcoin isn’t a theory in Africa. It’s practice. @BitcoinWitsand proves that real Bitcoin Circular Economies can be built anywhere, even in the middle of nowhere.

As president, I will make sure that your right to use and hold Bitcoin is inviolable. Bitcoin is not only a bulwark against totalitarianism and the manipulation of our money supply, it points the way toward a future in which government institutions are more transparent and more democratic.
