Binance was hacked before, yet it remains the number one exchange today. With Metawin, it wasn’t the game system that was compromised, but rather their hot wallet. I’m confident they’ll learn from this mistake and improve their security measures. They are hopeful the funds will be recovered, as they have been traced to HitBTC and KuCoin exchanges.
Nowadays, almost every day you can find information that some protocol has been hacked. And here it is important to look not at the fact of hacking itself, but at how the project team reacts. And if the problem is quickly fixed and it does not negatively affect the participants, then trust in them will increase in the same way as it was with Binance.
