I agree with you, I also believe in the CEX wallet exchange because I trade there every day with a fairly sufficient capital for my trading. so I don't use a cold wallet.
Exchange wallets are also safe if we choose an exchange that has a good reputation like binance and so far my crypto assets there are safe. Each investor has their own considerations in choosing a wallet to store their crypto assets.
Engaging an exchange wallet for the daily trading as indicated has some perks that are very hard to turn a blind eye on, especially if the platform chosen has a good standing in terms of security. That is why trust in a platform like Binance is a solid basis for the comfortable implementation of investment activities. However, assuring that the state of the assets is secure is something which should not be omitted. Checking through the array of options like two-factor authentications or, for instance, exchange asset insurance will provide the sense of relief.
Nevertheless, since the main operation takes place in the exchange wallet, it is not superfluous to study other options for storing funds, for example, in a small part of the total assets, as an additional measure of protection. This is good for ensuring that there is robust stability and security of the portfolio all through the period avoiding any complicating situations in the market, or any technical hitches that may be witnessed in the future.
