I'll compare this possible launching of their own stable coin to Facebook's Libra that has failed. They're both planned but not executed so let's see if PayPal will just remain on their planning stage and might end up the same as Libra's.
Paypal is the absolute definition of a company that should be using a stablecoin. Its goes against everything crypto used to stand for, but so does Elon Musk, and crypto 'investors' take his Tweets as the word of God. Paypal is also what made Elon all his money. So there is that....
Its not a dying service. Its used worldwide to send money 10x faster than a bank.
Also Libra Coin didnt fail. They changed the name to Diem.
