I might do it just for the hell of it and see how it goes.
If it's a scam as you said (and more likely it is) then why deposit even 1 sat and help them to continue their crap? Even if you deposit as a test, this will help them and not you or anyone else.
I've just checked the website.
the daily interest rate starting from 1.5%.
you could get $1360 from $1000 of "investment"
it's too good to be true, but it's not scam YET.
a scam is not a scam until it's scam.
with that big ROI, I doubt that this scam can run for longer than 6 months.
