It is probably more then this. If we consider the amount of people that have invested in altcoins and the devs have vanished after getting the money. I think we are probably over 10 billion losses. This is not a good look on cryptocurrencies and it is annoying that people are just out to get profit instead of trying to promote cryptocurrencies in a positive way. Some of these hacks were intentional and done by inside jobs instead of a person on the outside gaining access and I do not think they can be called 'hacks'
Rug pulls, hacks and scams, everyone is losing and it could be in tune of billions upon billions every year.
So this is the start of 2023, and sooner or later we will hear another bad news in the altcoin market including hacks from cyber criminals and I don't see it stopping anytime soon.
We may say that this is also part of the ecosystem, and as much as we don't want to hear this kind of news, definitely we might hear it again and again.
