Your suggestions on website

Hi, I bought a domain with the name fever bux but I am confused about which niche it would about. In the beginning, I was about to make it a site on biography but no I am looking for another niche for this domain. What you say? Looking for quality suggestions.

At first you have to Find out which topic you need, then buy domain. It's difficult without research fixed any niche.

Generally, Niche first, then Domain.
But in your case, look what the words in your domain are related to.
Analyse those niche and subjects and choose the best one.
All the best.
