I was wondering if there is such a thing as an intermediary service for receiving a fiat bank transfer (let's say from a friend, employer etc) and converting it instantly into bitcoin on my address? A friend told me about a service that exists for the other way around, so far i haven't had much sucesss on search engines. Thanks!
Bitwage is your answer, check this out: https://www.bitwage.com/invoicing but they not available for a worldwide. And I'm not sure the service not affected by bitcoin fluctuations, you need aware about this.
Or you can use coinbase merchant tool, but it's need required to set up the script, not directly like bitwage, the advantage of coinbase merchant tool is it will not affected by bitcoin fluctuations.
