Defi can't always be trusted by so many bad stories happened with the defi these days. I meant if we must aware with the fact that if defi can't sustain due to the various reason. Celcius has been giving us a very good lesson even a big defi can't even survive when it was coming to the margin call and low liquidity caused by being drained by someone who has been borrowing bunch of liquidity from the defi itself. I can say that if defi can't fully be trusted but trusting defi is still good for now.
any platform or network can't be trusted as they are vulnerable to either internal attacks or outside attacks. the security depends on how the team will continue to update their security protocols as hacking softwares are getting sophisticated everyday. just like any new network technology, defi can't avoid these attacks. hence, customers should always be cautious in storing their funds or managing their funds via defi platforms.
