Why would you compare a megasite like Binance with Metawin? They are worlds apart. Most investors including me were confident that Binance would recover easily after that attack, but the same cannot be said about Metawin.
Many centralized exchanges died after hacks or they took advantage of hacks to disappear like scam exits, we can not know their real reasons.
Exchange graveyard will make you more fearful of storing fund on centralized exchanges.
Metawin is a big platform with success and reputation, but $4M is not small money and it's good to see they quickly identified hacker wallets and took quick action to top up their wallets. It brings trust to their users that Metawin have deep budget for their business.
A next move for Metawin is internal investigation on what's going on, identify security holes that allow hackers to exploit their platform and fund successfully, and fix all these things.
Maybe the hacker was an idiot. Moving stolen funds to centralized crypto exchanges seems like a dumb move. The Metawin team identifying more than 115 addresses associated with the hacker also means that this guy(or several guys) was/were not that smart
It's really stupid to hack a platform and move stolen fund to centralized exchanges. Hackers in this case maybe think that they can deposit and withdraw their fund quickly from centralized exchanges while Metawin team are sleeping.
