buy low, sell high.
Maybe, depends on the situation.
Yesterday I bought some verge at 10 cents then more at 14 cents. It peaked at almost 30 cents, then backed off, now its at 22. If I sold now Id be selling High but why would I want to do that when it obviously has the potential to go much higher.
I agree with you, holding or selling of the alternative coins depending on the trend of the price, if the trend up of price is very strong holding is good choice because it will gives us maximal profit, but if the trend of price starts weakness will be better to taking short term profit because the price will goes down. So hold is not bad advice everything depending on the method the traders when investing in the digital coins holding is for long time investment and buy low sell high daily is for short term investment in trading activity.
