I also had 2000 $ ETH in Kucoin exchange.
However, due to the quick action of the team management, I did not suffer any loss.
You stated that "many lost their funds" but that's not true, nobody lost funds actually. Kucoin was able to recover most of the funds hacked according to them, thanks to advanced tracking and team efforts. However, Kucoin and all exchanges need to advance their security, this is because hackers keep devising new means to hack. All these hacks on CEX is the major reason why we shouldn't keep funds on exchanges long term, only for trading purpose.
Yeah, they do, they recover "84% of Funds Stolen in $280 Million Hack", that's according to the news.

However, they still loss 16% or 44 million usd, that's a huge money, and even if we say some of these are from customers deposits, but Kucoin were able to refund everything, so we did not hear complains from traders and investors.
