Just visited the site and it looks like scam but:
- 4 letter domain may cost a lot of money now... (that was registered in 2001 year)
- They have 5 day activity in Linkedin
https://www.linkedin.com/company/hbus/- .... and when you try to Google you find lots of news about HBUS and Huobi in US.
So maybe they are just in the beginning of marketing the project
Good luck with your project!
PS.: I need to hurry up with my currency exchange project otherwise there will be no space for it on the market
