Your explanation about DeFi and its importance is good, just as you said in DeFi, one has to be very careful when dealing with DeFi because once the private key is lost, which implies a loss of the total asset.

Funds are provided to users should incase a bridge of security

I don't totally accept this, there are cases of fraud that even the user ran to the bank while the transaction was still going on yet they couldn't do anything to it even when the scammer debited almost x10 of what the bank permitted for the user. But some centralized exchanges make provision for their customer's losses.

Thank you for sharing.
