For me it's very simple. I used paypal for years, several times. 5 years ago I heard about Bitcoin and never used paypal again. Not even once.
Why? I don't see Bitcoin as an alternative to paypal. If this is the case it is massively overvalued. Bitcoin is an alternative to country backed currencies.
Paypal is a service provider. Paypal could in theory add cryptocurrencies to its services.
If you ask my opinion, I still prefer PayPal as the payment medium mainly because the transfer is instant. I pay for services like social media accounts for promoting my business and the seller is ready to give the accounts only after receiving the payment. Thus by using PayPal, I can have faster access to the product I am buying.
