It's far, far less widely accepted, though. Which makes it rather less useful if your primary use case for money is to buy things.
Edit: For me converting BTC in funds I can use to buy food (not just for myself but also my kitty), pay my bills (rent, electricity, gas, water, internet, mobile, AWS) is a pain in the ass.
Sure there are online stores they will accept bitcoin, but not my local supermarket, sure some isp’s will accept butcoin but then I’m limiting my options of who I can use.
With PayPal (yes I hate them just as much as everyone else) I can get an invoice paid and have the funds in my bank account seconds later.
I like the idea of a decentralised Payment process. But atm it’s not for me for a number of reasons not just acceptability.
