After giving so much profit back, it is a matter of concern how long this project will last. These websites give new user funds to the old members and after a while they run away with a big amount of money. Because no real company can give such a huge amount of profit everyday. They promise huge returns so that new crypto investors are attracted to the lucrative offer in the hope of making a quick profit. And their decision puts them in great danger in the future.
After checking their whois information I understood the website was already created months ago and they started the scam project recently. They way they make money is simple as you said buddy. They don't give any profit to the investors they just take money from the new investors and give it to the old investors. After a new weeks, people will think they are legit and trustworthy so they will invest more money, they can run away after taking thousands of dollars from the victims.
