In real life, with Gold, there is nothing can replace gold, for thousands of years. In digital assets, there is nothing can replace Bitcoin, that is a King and a backbone of crypto currency ecosystem. Libra, is a stable coin, so its price does not change too much, like what we saw with Tether USD, or USD coin (nearly unchanged), but Libra holders might have passive rewards that paid via Libra (I guess so). Therefore, investors can get small profits from Libra, not too much, in my opinion. Therefore, to maximize profits from investments, I don't choose Libra.
