This is what we always worry about, even though we have completed all security requirements when on exchanges but because of data theft from various sources then all security systems are useless, this is what makes decentralized exchanges more attractive and I prefer to use Pancake swaps if I want to buy or sell coin.
Everything can't be done on pancakeswap, pancakeswap is only a decentralized exchange that allows you to trade cryptocurrencies and tokens without a centralized intermediary. Conbase and several other major exchanges such as Binance have features and advantages that will make crypto transactions easier. The security used is also getting updated and getting more secure. Security is not a guarantee that it will continue to be safe, but at least the big exchanges are safer and more trustworthy for our personal identities.
