This is one of the many mismanaged exchanges which have turned rogue. You have Yobit, Bittrex, Poloniex and more on the list.
Then you have the scam angle to consider here. The exchange is run by humans like us, prone to taking what's not rightfully theirs.
The "360k frozen" are just words you see on your screen. Holdings or assets, as the screen shots say. Your actual BTC are now probably paying for someone's lavish lifestyle.
Let's take this to its logical conclusion already. I will since I am seeing no one else do it.
In a free market where there is a LOT of money to be made transacting in cryptocurrencies, why is it that so many cryptocurrency exchanges 1) eventually end up ripping off a large number of the people they service, and 2) end up having extremely terrible customer service that guarantees they are able to easily rip off their customer base?
At this point in history, one would have to be a complete idiot to not realize how much more money is to be made by simply providing quality exchange services. How hard could this possibly be, to run a legitimate business? Look at the profits that Schwab, Fidelity, etc. have. Who wouldn't want to be in the same boat? All of the exchanges out there have this golden opportunity in front of them right now.
So why are literally all of them dropping the ball?
My conclusion is that this is organized and intentional. Many of these exchanges were likely incubated by the same entities. Who else? Venetian "noble" families that have been engaged in usury since the Crusades. Aka, European royal families. Aka, the Fondi, who were originally from Rome. They control the BIS and the 162 private corporate central banks worldwide. They have more than enough money to engage in the creation of millions of these crappy little crypto exchanges.
Consider, too, that several of their central banks are right now developing their own private cryptcurrencies and blockchains. These currencies and central banks will soon be competing with the crappy exchanges that they intentionally incubated and created.
Sure, go out there and make a ton of money in cryptocurrencies. But then guess what? The Fondi-created exchange you are using is going to steal that wealth back from you, courtesy of the Fondi. They can't have folks running around with new wealth, when the UN Agenda 21 plan is global wealth redistribution, communitarianism (aka, communism), and deeper debt slavery among populations.
So, they created the entire paradigm of cryptocurrencies to get the masses excited about the prospect of a cashless society where all financial transactions are tracked to the individual, forever. They created this excitement by ensuring people make quick wealth. Then they steal that wealth back from you via their crappy exchanges.
Then -- the cherry on the cake -- once you have lost your shirt from having your life savings in cryptos stolen out from under you, they introduce their corporatized central bank cryptos for you to enjoy! No theft, fantastic customer service, and they'll even let you invest in your 401K, tax free. Oh, and let's not forget that these cryptos that you are excited about just destroyed your ability to do any level of financial transactions in private.
How's that for a communist-style dialectic? Rinse, wash, repeat. The masses have fallen for it for the last 1,000 years. Why not 1,000 more?
