On June 19th, Marc Fleury, the founder of the US open source pioneer JBoss and founder of FreeSide Funds, said in the Babit online live show She Knows that BTC and ETH might benefit from Libra because they are all "cryptocurrencies." Libra may bring more legal currency to the cryptocurrency like the USDT, provided that the exchange can trade the fiat currency and Libra trading pairs, as confirmed in the white paper. More currency will create advantages for all currencies, especially mainstream currencies. Since Libra is entirely supported by reserves, it is necessary to include the US dollar, the renminbi or the euro in this system. Therefore, it is an efficient legal currency and will bring new liquidity to the cryptocurrency. This is better than the USDT, so it is generally optimistic.
