Generally though, I think the message OP is trying to pass is that crypto users should stop storing their funds in centralized exchanges, this one message is one that can never be outdated as long the crypto space continues to exists and newbies continue to join the space, ive had this experience when cryptopia exchange got hacked, I lost almost everything I had then and had to start afresh again, this experience thought me a vital lesson and till today, I never leave my funds on centralized exchanges anymore, I rarely use them even, except on days I decide to do some trading.
We have to convey more to people who don't know that a centralized exchange is not a safe place for us to store assets, I think there are still many out there an investor who still keeps assets on the exchange, especially a beginner who comes for the first time, of course, will definitely choose an exchange over personal wallet to store it but this awareness sometimes makes it difficult for us to tell those who have been hypnotized by the exchange because of its convenience even though behind all of that there is a big risk that awaits.
