It appears Bitcoin Gold (BTG) has been double spend attacked over and over again, totalling something in the neighborhood of $18 million at current prices. BTG forums seem to have been tracking the hack, going as far back as last week, monitoring the controversial coin’s hashrate, ultimately determining a 51% attack was under way.
“An unknown party with access to very large amounts of hashpower is trying to use ‘51% attacks,’” Bitcoin Gold forum poster Mental Nomad announced a week ago, “to perform ‘double spend’ attacks to steal money from Exchanges. We have been advising all exchanges to increase confirmations and carefully review large deposits.”
