I can argue the fact that all centralized exchanges are vulnerable. For example, CEX.IO and Kraken were never hacked for the entire history. And these exchanges are large enough. I even don’t mention local platforms which are designed for specific countries. You can check Bitcoin.co.id review on CryptoHoo (the exchange works with Rupiah specifically) or read other qualified authors to find reliable small platforms. Decentralized exchanges are cool, too, but we shouldn’t blame centralized ones and ignore them at all, I think.
