Go and ask all the people who were getting 20% returns on Celsius how "guaranteed" their returns are. The fact is that nothing which is offering those ridiculous returns is risk free, as thousands of people have recently found out by losing everything.
Exactly! I was extremely reluctant of participating in Celsius offerings. Realistically speaking such a public business with wide reach like Celsius offering 10-20% APY must raise some red flags. In traditional finance higher returns = higher risk. While that might be true in popular, widely advertised opportunities/businesses/assets, risk is subjective to the knowledge and experience of the individual.
I don't want to put straw on fire, but if people actually read the terms & conditions of Celsius, it was clearly stated that Celsius can/will lend your crypto to third parties. But let's be serious, how many retail "investors" actually read the T&Cs? That is why Celsius had a massive focus on their marketing game --> Offers upon offers, bonuses over bonuses just to put your money in there.
