The Libra stablecoin and the Libra blockchain pose direct challenges to the existing financial market infrastructure. Facebook is not deemed a responsible operator of this huge social network. Facebook used to forbid crypto ads in its social network for a long time. Facebook has been criticized in this circle for its censorship policy in the crypto area. Mainstream financial institutions recognize this and therefore will not endorse the project. This is why no banks have joined Libra so far. Stablecoin is in essence a product, when it is brought to the market, it is expected to generate reasonable profit.
