In terms of facebook's libra coin, I think France and Germany will not contribute that big to the development of the coin, since facebook is a social media, people who are using facebook will be the big subject to it. Let us consider the country like india as the top facebook users in the world 2019 based on https://sproutsocial.com/insights/facebook-stats-for-marketers/. The top users will have the biggest impact on the libra coin as they are the direct subject to it.
PayPal being one of the companies that has promised support for the Libra coin is already backing out of the game already and I think that is already a very bad omen that Facebook coin may not succeed. Most of users who would have made the Facebook coin successful will also fear that the government would have issue with them, so they might not really support also.
