CAUTION Theft of cryptomoney ''hackers or scams"

They're the seven biggest cyber-traffickers. The value of the cryptomoney stolen in the last five years exceeds 1,530 million dollars (1,237 million euros at the current exchange rate). Everything serves as learning for this nascent business.
The latest cyber-attack has been the most succulent: the 523 million Japanese XEM stolen is equivalent to the changeover of 432 million euros. This has led the Japanese Financial Services Agency to inspect the kryptonite markets and to require Coincheck to optimise operations.

All over the world
Coincheck is the cyber-cracker exchange house on Friday in Japan. The firm has reacted fairly quickly and, after reporting the event, explained that it will reimburse the missing assets with its own. The 260,000 affected customers will receive the equivalent in yen.

The theft of Coincheck is just the latest on a list that will grow irretrievably over the years. So far, the worst cyber-attack has also occurred in Japan in 2014, when Mt. Gox saw 850,000 bitcoins - the equivalent of 389 million euros - disappear.

Parity Technologies, from the United Kingdom, with a turnover of 227 million euros in exchange, completes for now the podium of the largest cyber-drugs. In 2017, he found that his multi-signature Ethereum wallets were frozen and blocked access to one million ether digital coins.

The other four
The other four major virtual coin thefts are more discreet. Fourth is the Slovenian-based mining service NiceHasch, which in 2017 was robbed of 4,700 bitcoins (65 million euros). The fifth is the Bitfinex platform in Hong Kong, where 120,000 bitcoins (58 million euros) disappeared in 2016.

The sixth cyber volume attack (2016) affected the whole world. The decentralised autonomous organisation DAO, an experimental investment bank based on the Ethereum system, suffered the loss of the equivalent of 43 million euros. Finally, in 2017, Tether, a virtual token currency system linked to the US dollar, lost 30,950,010 tokens (25 million euros).

I already know that this is news that many people know about, and I'm not including the most current ones. However, one thing I have learned in this life is that where there is something of value there will always be someone who wants to take it dishonestly, and 2017 was definitely the time when cryptocurrencies acquired the greatest value in their history, this prompted the creation of cryptomonedas for the scam, plus many cloud mining pages that promised great profits in BTC that closed their doors without warning. Some places are obvious and easy to avoid, but suddenly exchange houses with quite some time operating and a reputation gained began to be robbed. They all report the hacker attack but could there be anything else behind the curtains?

This is just a hypothesis in which not all exchange houses are victims of the attacks, if I am not mistaken so far this year there have been more thefts of cryptocurrencies than in any other, at the beginning of the year was decreed a war without truces in which prices began to fall so for many it was logical to start withdrawing their crytocurrencies. If you are a bureau de change in which many users have deposited large amounts and you know that there is a massive withdrawal coming in which you could have losses (when the user withdraws his cryptocurrencies the bureau de change must pay him in real currency) then there is a high possibility that the house will say it was stolen being this false or even in agreement with the thief leave the door open so that it can enter without problems, this is an uncertainty that we hardly get to solve but that falls within the field of the possible. In these times I more than ever recommend that we keep our cryptomoney in cold wallets because whether the robbery actually happens, or the scam happens in the end we are the ones who lose!
