The only reason why Defi is acceptable in the eyes of most coiners is the fact that its so easy to use to swap for wrapped tokens. That way you can keep your funds out of an exchange and be completely self reliant. No third party is involved in your trades or your wallet holdings.
The bad news is that the underlying blockchain (BEP20 or ERC20 for example) is not as trustworthy or reliable as Bitcoin blockchain. And obviously it is not one and the same thing.
Its like giving someone a piece of paper with "1 Bitcoin" written on it and the person reassures you that that paper can be traded in for 1 Bitcoin at any time, as the piece of paper itself has an underlying Bitcoin reserve value. But its still not 1 Bitcoin. Just a voucher for 1 Bitcoin.
Should the underlying DeFI's blockchain fail for some reason, your wrapped token will become worthless and nobody will trade you 1 Bitcoin for it....
So whether or not you want to trust Defi is up to you. But one thing is certain: DeFi itself is trustless and verifiable. Just not without risk, depending on which blockchain you use.
That's certainly true, mate. Most underlying blockchain networks aren't as decentralized as one thought they would be. They're extremely vulnerable to hacks and/or manipulation because of their focus on performance instead of security/reliability. There's no guarantee your balance will always be there on a "De-Fi" platform of your choosing whose underlying blockchain network is centralized. While Ethereum is the most decentralized blockchain network after Bitcoin, that doesn't mean it's perfect.
You're going to have to decide whenever you'd want to put all of your money on "De-Fi" or banks. The latter is a much safer option, although rates are lower than those provided by "De-Fi" platforms. At least, we have an alternative to traditional banking. As long as we have Bitcoin, nothing else matters. Just my opinion
