Dear newbies, please treat exchanges, such as Binance, KuCoin, Kraken, Huobi, OKX, and Coinbase, as marketplaces. What do I mean? Just as you do not leave your goods on the market after you have paid for them, you take them home with you. Consider your coins as the goods you bought at the marketplace. Your bitcoins should only be stored in cold storage wallets after purchase, and transferred out when you want to sell them. It takes less than 10 minutes. Remember, if you don't have the keys, it's not your coins.
This advice has literally been said hundreds of times to beginners or anyone who has deposited their assets on the exchange. I don't think things will change especially many active traders will not care about this advice because they believe that as long as they are still trading then having assets on the exchange will allow them to take advantage of opportunities much quicker.
Your advice is more suitable for investors or for those who have not traded anything on the exchange for a long period of time. So don't equalize traders and investors even though it is true exchange is not a completely safe place for our assets.
