you should not start monetising your blog before it hits AT LEAST 100 unique visitors daily
try to get to 15-20 articles,create a proper keyword structure and then you can decide what sort of affiliate programmes would be predominate
hence if your blog is article based,not "news" (usually rewrites of other sites) I would suggest you chose one of the niches:gambling (plenty of excellent affiliate)
security and protection (VPN,VPS,proxy etc. affiliate),trading(exchangers,exchanges affiliate)
can't stress it enough-create unique content first,get visitors interested in your site
if it gets search engine traffic you can go for Adwords or any bitcoin ad network
