CoinMarketCap allows for ads to start at $100, not the previously mentioned $50. It does not appear that advertising can be "geo-targeted" on CoinMarketCap.

If we want the advertising directed at people within the UK only, we will have to discuss google Adsense or some other advertising that allows advertising to be targeted to geographic location. Both facebook and twitter do allow for geo-targeting advertising to my knowledge but of course, we are all open to other ideas.
