@teh_g thanks dude. I've been doing a bit of bing ads but to generate a reasonable amount of traffic (in cryptocurrency) costs about 25p per click - which would get quite expensive at the end of the month 😉 and there's no revenue from the site yet.
Twitter is being a bit slow too seeing as I have < 100 followers.
I'm a little lucky and I just host my site for a handful of people to chat on, so I don't need to worry too much. I did a bit of Google AdWords with some free credit, but it did nothing for me.
