This is the sad truth. After Voyager collapsed, there were warnings everywhere to withdraw all your coins. And yet loads of people lost everything when Celsius collapsed a week later. And again when BlockFi collapsed. And again when FTX collapsed. And loads of people will still lose everything when Huobi or Kucoin or Binance or whoever collapse next.
This time they will lose more than our imagination because if any of those exchanges collapse then the amount of damage will be very intense for the users who trust custodial wallets blindly and are very lazy that they don't create their own wallets to and move their Bitcoin into those wallets.
Ignore what is or is not being said and get your funds in to your own wallet before it is too late.
Yes, that advice is the best one! Just ignore the words of all those exchanges and move your funds into your own wallets as soon as possible. It's always better safe than sorry and if someone doesn't move the funds now then he/she will have to bear the consequences of his/her arrogancy.
