Should Libra be used for social media the way steem is used then obviously it will affect steem. At the moment it doesn't seem to be so. But you will never know what it will be used in the future for.
Despite the assurances given by Zuckerberg, personally I do not trust him at all and do not intend to use the Libra. I also feel that people are making a mountain out of a molehill by saying all kinds of things about how successful Libra is going to be.
Having said that, I do think that Libra, if successfully launched, will provide the cryotocurrency market some level of boost, albeit not the level projected by some people.
Thank you for sharing your insights dear @devann :)
I think that people are so confident about the success of Libra because there are biggest corporations behind this project, including MasterCard and Uber. They perfectly know what they do. However, everyone sometimes fails, especially considering the fact that they don't have experience in this industry.
