According to the official blog of the cryptobirge Gate.io, on January 10, an anonymous hacker returned $ 100,000 in Ethereum Classic (ETC) cryptocurrency to this exchange company, without giving any explanation.

Those responsible for the 51% attack on the Ethereum Classic blockchain returned $ 100,000 in tokens.

51% attack – the work of the white hacker?
The cryptobirge team Gate.io tried to contact a hacker (or organization), but their attempts were unsuccessful. Thus, the exchange could not get any explanation about the motivation of this incident.

Now, Gate.io assumes that this campaign was aimed at pointing out the risks associated with the use of cryptocurrencies, trading and security of the blockchain based on the Proof of Work protocol.

The Gate.io article states:

 “If an attacker does not use this for profit, then he may be a white hacker who wants to remind people of the risks of blockchain-consensus and security, which is based on hash power.”
The Gate.io team also explains that the possibility of such attacks always exists, since, in general, hash capacity leasing to get 51% control over the blockchain is relatively inexpensive.

In order to avoid further attacks, Gate.io followed the advice of the developers of Ethereum Classic, which was posted on Twitter, and increased the number of transaction confirmations to 4,000, and also took a number of other measures to enhance protection.

Skeptical reactions
The Twitter community’s response to the “possible good intentions of the hacker” was extremely critical and skeptical. For example, Mati Greenspan, chief analyst at eToro, pointed out that the amount returned is too small compared to the amount actually stolen.

Coinbase Exchange found that there was a double waste of $ 1.1 million, and this article says that $ 100 thousand was returned.”

Others stated that it could hardly be called the “knight” of the one who robbed the bank, and then decided to return the money.
