Buy the rumor, sell the news. So if your actions on the trademarket are based on news then you might get burned seriously. Did it a few times myself in the past, did not enjoy. I do look at charts in the sense that I won't go near coins that have been pumped recently as a subsequent drop is usually around the corner in that case. There's no technical analysis involved for me personally, its more like simply 'eye-balling' actions on the cryptomarket and only with (alt)coins that are more or less established.
