If you talk about utilities and will pay someone for his services, then there are many people willing to accept with any coin, even they also accept paypal. But here discuss about a currency that can be owned without identity, self-controlled or not centralized. All these things are already owned by Bitcoin, don't you know and turn a blind eye to the use of Bitcoin from real use? .
Yes you have many good points. I don't even think Libra will make in onto coinmarketcap now as it may not be accepted as a genuine coin by them.
paypal
I bought my first bitcoins with paypal...
Because there are many people, communities, shops, e-commerce, companies or anyone who can be paid Bitcoin for services and other things
You are correct. I'm thinking thousands versus Millions here. Its no more than a prediction. But I got my first bitcoin in 2011 and sold all them in 2017. Call it luck or intuition. I just have this belief in Libra that it will work for me..
