So instead of actually debunking his arguments you published a handwavy reply? I very much think that if someone is offering insanely high ROIs but does not divulge how the value is created, you can safely assume it's a scam, and simply pointing out the disparity suffices as proof to me at least.
I don't know what happens behind the scenes at Celsius. I do know there are many ways to get those high ROIs in DeFi. With zero evidence suggesting they are lying about returns, the charitable guess I can make is that they are getting high DeFi returns and giving their customers slightly lower ones after taking a cut.
I guess the charitable explanation for them raising capital as expensively as possible from randoms on the internet is they're feeling charitable themselves. I seem to remember that was how all the pre-crypto HYIP "investments" explained the generosity of their compounding daily return offers
