thank you for providing a useful link, so this is their reason why invetor has to pay $ 2 for KYC:

Why is there a charge for KYC and Accreditation Checks?
We made a decision at the start of this project to minimise all unnecessary costs to help improve the Return on Investment we can offer our token holders. This includes not paying for KYC checks for investors who are unlikely to buy tokens. The $2 KYC charge just covers the cost of the check and will be reimbursed with MBTX at a discounted rate.

this would be beneficial for the project, but not friendly to investors, this is just my opinion. besides that I personally have some bad experiences with mining projects, I hope this project is different from some of the previous mining projects
