To buy bitcoins I use the
Bittylicious website.
I've used it lots of times on backpage and have not had any problems and I can customise the amount of bitcoins I have to make sure I can spend under ?10.
You enter the amount you want and it matches you up with someone who can sell them.
I use the "bread wallet" (an app on my iPhone) in conjunction with it and it is relatively simple
I've stopped paying for back page in all honesty. I just delete my old advert and make a new one, (Lots of work but I'm stingy)

and Its mostly just a copy and paste job.
It does make me wonder. Before back page used to post my advert in lots of different cities but now I noticed that you have to pay to appear in extra areas at 25 pence each.
Has anyone noticed if this has made a huge difference to the amount of work that they get?
