The week began with the news of a 51% attack on the Ethereum Classic network, which the attackers purportedly executed undetected over several days. The attackers managed to pocket the US $5.6 million through double-spending. The network was attacked again on Thursday, with the attackers ripping off US $1.6 million. The attackers were able to mount up sufficient resources for the attack by spending a mere 17.5 Bitcoins worth US $192,000 for renting the required hash power.
