Bitcoin hasn't been fast or cheap for a very long time, whereas many 'traditional payment methods' let people send money instantly for free.

Well, not really free. There's a cost associated, but it may not be initially applied to the consumer. It makes it's way through in some way though, such as an increased service cost. The most transparent industry for this is likely gas stations, which in the U.S. at least (and even then I can only comment on the regions I've observed it), they will quote different prices per gallon for cash and for credit/debit, which is them pushing the cost through to the consumer transparently. This was actually disallowed by card processing agreements in the past, because card processors didn't want the fees hampering acceptance of charge cards.

Paypal can do both of those

Paypal can also close your account at the drop of a hat, and has a very nice long list of things you can't do with your money when it's connected to paypal (a list of things which will get your account close and your money confiscated in some areas).

You can also throw stupendous quantities of cryptocurrency in the bin accidentally. So there's that.

Trade offs I guess.

PayPal doesn't work globally.

Neither does Bitcoin

In which country do cryptocurrencies not work in? They work in every country in the world. They are used a lot in Venezuela for example.

According to this[1] around half the people on Earth don't have internet access.
