Hi please appraise my blog (money making niche)

Hi

I have recently registered a domain http://howto-makemoneyfast.com I am planning to blog about money making niche as it my field of interest

I wanted to know your view on this blog, the keyword "how to make money fast" is search 50k times exact match with medium competition, all other combinations of the keyword are booked even .org .net are booked

What is your opinion am I on right track? if I blog regularly what are the chances of success also ..do give any advice you feel like

Thanks in advance
