I had been warning about Celsius for months, in fact I even published this blog post last year: https://rorodi.substack.com/p/the-biggest-crypto-lending-com...
Also posted it here on HN but it did not get much traction. What really baffles me is that major VCs have put hundreds of millions into what pretty much every one who has watched one or two episodes of "American Greed", would immediately recognise as being a ponzi scheme.
I e-mailed the regulators, the VCs etc... They did nothing, and now it is too late.
