This is de-fi if I'm not mistaken
"DeFi" is a meaningless buzz word. The majority (or indeed all?) projects which styled themselves as DeFi are not decentralized in the slightest. How can it be decentralized with a centralized third party can disappear with all your coins at any moment? Same as the term "DEX". I can count the number of exchanges which could genuinely be referred to as DEX on one hand, but there are hundreds of scam platforms out there advertising themselves as DEXs and enticing people to deposit their coins to buy the latest shiny shitcoin or stake for some obviously unsustainable return.
Out of interest, here is a post I made about DeFi three years ago:
I haven't spent a huge amount of time looking in to DeFi (so perhaps I shouldn't really comment at all), but from what I have seen, it seems to me to be exactly as you claim - unbelievable rewards and gains. Until someone can prove to me otherwise, as far as I am concerned it is essentially going to be the same as the ICO craze. A minority of lucky people will make very good returns, a lot of people will lose everything or almost everything they put in, and in a year or two 99% of the projects/coins/tokens will be dead and forgotten.
Seems like I was proven right. NFTs are already well on their way to the same fate, and the craze of bitcoin ordinals seemed to be over within a few weeks.
I'm sure it will only be a few months before the next craze of shiny trash comes along to help people rapidly lose their money.
