The really crazy and suicidal moves is to keep your currencies in central exchange platforms. We must learn from the mistakes of others and learn that exchange platforms are not a safe place to keep our wealth inside. There are many alternatives through which we can keep our currencies safe during the bear market so that we do not wake up and find that the exchange platform that we trusted has gone bankrupt or has been hacked, and one of these alternatives is a hardware wallet such as Trezor or Ledger.
But this is bad, Initially when I joined the crypto space newly I was thinking that this exchanges are digital banks and therefore acts as banks in this industry, but now seem this is becoming opposite because most of them have now turned out to be a clear scam exchange, and this is why we need regulation to protect investors, hence if this platforms should get away with this act, it doesn't mean well for the entire industry because so far crypto is currently not been adopted and regulated world wide, we still need them as medium of exchanging our cryptos into fiat.
