I'm not sure internet native is the best word usage here. I would say it's a race to find the best, most anonymous most transparent and easiest to use currency for online payments.
I reckon the world would slowly turn into one with 2 payment methods, which make up the majority of transactions across the world. One for online purchases, like items from Amazon or buying in game currency for a game and the other one to be used in real life situations.
Anyway. If there was truly a race as described, Bitcoin would be winning it
I like the term internet native currency. Native means that the currency originates from the internet and internet is its natural environment. And this is true for all currencies mentioned in the article (bitcoin, Tether, Libra...)
Cash cannot be internet native currency, because you can only transfer it physically. Credit cards don't originate from the internet and the problem with PayPal is that it is not universally available because you needa bank account to open PayPal. Internet should be available to everyone.
