small words, but if that is the case, then would/could Libra replace Bitcoin as a store of value coin also?
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.
This is an open secret that there is nothing like gold in the market. The value is really stable and it is deflationary which means that even if there is some financial crisis, the value stored in gold would not degrade or depreciate. Libra would have a stable price of course but it would not be the gold for the digital gold is Bitcoin. However there would be very high implications of Libra once it is out in the market.
