Building a website. Is it worth it?

I am building an automated Instant SMM services website, and hope to get it ranked highly on Google. I am going to use SMM and SEO to get traffic to the website. The niche is Instagram, Followers like & Views. Is this too competitive a niche to realistically get it ranked? Should I go for something else instead?

Yes it's pretty darn competitive. That's not reason enough though (in my opinion) to give up.
