Hello, New to Bitcoin and what I would like to do is simply pay for a few monthly bills online, Only about £30 a month in total and was thinking of using
the Green address app for my phone. Would this be a safe way to go
Why don't you use blockchain's mobile wallet app? That is quite secure i guess because i used it before sometime on my smartphone and had no issues with it and it was quite fast as well, not using it anymore though so don't know how it works right now.
