EarthCoin (EAC), one of the "classic" altcoins that has been here since 2013, was controled by a group of hackers for several months, who did not let anyone else mining this coin. Any attempt to extract a block of this coin failed up to now - all the blocks found by someone other were promptly orphaned. The original EarthCoin developer team did nothing to stop this mining monopoly, so we have decided to take the initiative and get this coin out of the clutches of those evil miners.
Do you know who were those hackers and what mitigation you have done so that it won't happen again? What are estimates of damage.
