Guys seriously?

Domain owner hidden, server whereabouts hidden by cloudflare, nothing about who is responsible for the website and even no data about it in the "business plan" that was available on that website imitating stock exchange you could buy coinex shares.

How many more warning signs you needed to understand that it's not good place to do business?

Even if the hacking was true (which doesn't really matter, because it's the owner's fault that they didn't secure the website), this is what this all scheme was about - if there are troubles, he can get out of it quick with as much money as possible and you will have a lot of problems locating him and getting something back from him.

Start doing business with people that have a legitimate registered company (not another privacy heaven company), is regularly audited and don't hide their identity behind everything that is possible, otherwise you will be screwed again and again and again.

Nobody of them gives a shit about you, because you will be just complaining here and complaining, and even if you finally fill a lawsuit you will have a hard time proving who it was. Even if somehow you manage to do that, he will just say that his identity was stolen, or some other crappy excuse that will make him 100% immune to whatever claims you have. And you agreed to that when you started traiding and mining on the websites that had all that scam warning signs that you so happily ignored.
