I saw much news about launching P2P buy/sell platform or many exchanges like Binance, Kucoin, Coinbits, etc. I visited many of them but I am confused about the mix of completely such transactions can an experienced person explain A2Z about the process?

I am curious to know, how Exchanges treat the stolen money or hack money? Are they really aware of it? Just think, your fund has been hacked and transferred from your wallet to another wallet and then it's deposited to an exchange. If you claim to the exchange about the money, Are they not responsible for taking necessary action? What do you think?
