Say what?!
I just wonder how is possible to even think that you can fool someone with these nonsense interest rates...

P.S: Put your money (do you have any?) into your marvelous project and be rich in a week. You don't need anyone's money.

I'm surprised that it's still up, this kind of project usually lasts just a few days, two things either you still have not found a big investor to scam or you have not yet recovered your cost for setting up this HYIP because you are only getting small amount fo deposit, either way, you will eventually take down the site after you have enough money to scam, hopefully, no one falls to this obvious scam.

there is a reason why his hyip/ponzi site is still active today, and the reason is as follows:

the guy is adding his ponzi site in several places and with that he will undoubtedly be able to steal money from someone that's why he hasn't deactivated the site yet

this is a topic that has been discussed several times in the past, it was a topic that generated great conflicts between members of the forum. but I will leave my opinion on that.

when someone hears about bitcoin for the first time and arrives at this forum and comes across a hyip site, that person may think that they will have a lot of bitcoins fast when investing in these sites. anyone who is entering the world of online investing with naivety will fall under the false promise of high return in a short time, and the situation can be worse if that person finds the site here on the forum because they will think that the site is here on the forum then it must be a reliable site. and will invest in the Hyip site and will lose money, so it is necessary to warn people


true, but there are many sites that do not give good advice, causing people to invest in these hiyp sites

All you need to do is read a few previous posts to find the answer to your question.
Consider if someone is able to make such profits, does he need someone else's money? If he could earn 850% in five days, even with just one dollar he could create a fortune in two months. I is obvious scam.

This interest rate seems unrealistic to me, I have not come across any platform paying such high-interest rates I will wait to see a review from those who have benefited from this system before making any financial commitment.

"350% After 3 Days" just how does your mechanism offer very high profit to users? If this isn't a scam, it's a ponzi scheme.
