ETH peaked at 1:40 pm @ 1353 before taking a dive to 1300, so my sell timing was very good.
IMO this was a classic buy the rumor sell the news situation: inflation was obviously low, so the yesterday's CPI would be good. So people bid things up. When the FOMC news was indeed good, a few last minute buyers bought, but overall the traders had to reverse since they had already gotten long during the rumor phase, so the price collapsed soon thereafter as a result.
