I mean, since PayPal already allows the trading of a few cryptocurrencies, then by definition it's already a "crypto exchange".
And I realize that a lot of people are excited about this, but I just don't see why. Skrill has done the exact same thing some months ago, and no one turned this into a big deal so PayPal should be no different.
There's a huge difference though, and that is that PayPal already has 346 million users[1]. While the crypto trading service isn't available for everyone yet, just imagine how much people would have exposure to bitcoin. They wouldn't need to install and register on a separate app for their bitcoin purchases.

https://www.statista.com/statistics/218493/paypals-total-active-registered-accounts-from-2010/Honestly, you made a really good point here, only the amount of users PayPals has is way more than the best crypto exchange (binance) has,no doubt it will definitely give bitcoin the kind of exposure it needs to become a global currency, PayPal will be able to reach out to more people than the crypto exchanges could, there by increasing mass adoption of bitcoin, and on top of that making buying, selling and holding of bitcoin much easier, cus they can do all those on just one platform.
