The project reveals that it is a scam in all its forms. It is definitely not necessary to invest, I did not want to waste more time and research about the project when I briefly examined their site because when you examine the site carefully, you can see that the project is carp hunting. Especially in today's market conditions, I would recommend you to invest in existing and successful projects instead of investing in such absurd projects. Tell your sister, too, that she should deposit money in vain and not be upset afterwards.
