That's my point as well. Ethereum's Vitalik, Binance CZ and many other influencers are embracing the decentralized exchanges but we are also hearing the news of security breaches.
Exchanges, may it be DEX or CEX are not safe from security breaches. Based on statistics, there were more hacking on the centralized exchanges and the recent one is Cryptopia which myself is a victim since i have not recovered my funds though not that big but still it's frustrating. My view on DEX is that we control our account which for me is important since that is our very own money and should not be trusted to companies that run centralized exchanges. CEX though they emphasize more on their security but still they are the ones controlling the funds of people.
We've heard a lot of hack attempts about CEXs. But I don't remember much about DEXs. I think Bancor and Cryptopia are not nice options to be evaluated in this process.
