Not that much effective but if you do have lots of time for a site owner then you could eventually do this stuff but if not then there's several or couple of guide/review sites which is far more better among the rest which it had been trusted and been preferred mostly by the community or people of this forum like Btcgosu and Gamblingbro.Im not saying they are the best but currently these are the names which people been recommending when it comes into this key area and as i mentioned earlier on which if people cant find out any interesting or something new in relation with these review or guide sites and just simply spamming their ref links then expect on what would be the outcome.
