sorry for the late reply there both relative new sites,but topsport has dropped from 9 million to just above a million on alexa and now just starting its SEO.it links to some good edu sites plus jaime oliver and has over 1000 backlinks mostly social .thebitcoindata is much the same but a slightly higher alexa rating 2.2 million.Within 6 weeks they both will be below a million.If you join now your price wont move as the SEO gets better so its the time to get in.Just now I charge a dollar a day depending what size you want and thats cheap for these sites.
I am starting a campaign with google adwords and facebook to advertise them just not got round to it as i manage 15 sites
