So much money. If all exchangers works togheter then for clear we can somehow find who stole it and exchange it if they exahnge it.
Although the exchanges work together, they aren't able to prevent this from happening, there are many ways for hackers to bypass them. For example, hackers can disperse the amount that they steal then use mixing services, which can be detected but quite difficult.
How can they prevent this from happening, there's no way for that to happen. Hackers are better, and we had information that some hacks were a possible inside job. We talk about huge money here, $1 billion is a lot, but I wonder is there some statistic for banks and how much money was stolen from banks and some other institutions!? I would like to compare stolen funds from them too! Then this post would be complete!
