Market is trending upwards. Never go against the market.
wrong. Buy in red and sell in green so yea you should sell and take regular profits despite all the ppl screaming hodl

That's a prudent piece of advice. Obviously if you want some profit in trading with digital coins, we should keep an eye on their movements between Red and Green areas of the graph. It is not always good to go with the flow, sometimes we need to stand alone in order to enjoy the drastic profit.
