Well it already scream scam when they even don't check their spelling,
I am not advocating for a new site but for any website a typo mistake can not be a big thing. Anyway, when I see a business is returning 1500% after one hour or 600% after a day then it's obviously to good to be true. When you are trusting something too good to be true then you are likely to get scammed.
But still though, if you wanted to have a "perfect" site, you should at least know how to spell correctly so that it will really look genuine. And if you look at how long this site is, mostly they have notice it already but they doesn't care because all they want is to scam people.
And not only that, the guaranteed profit is also another red flag.
Yes, it could be a Ponzi scheme, a Bitcoin doubler, so we should stay out of it.
