From what i see and hear and alsk have had experience, there are several mistakes that investors always do, first is they tend to think that they already know what they are doing without relying on the charts, they tend to speculate more rather than do analysis. Second, they tend to be greedy, they rely on their speculation that a certain coin will go high in value, but failed to do further research on the coin, they might bought it at a low price, but it may not go higher than they think, and they might just be set up for a trap. Third one that is see, is they go with the flow, they invest on the hottest coin and again failed to research the coin as well, theh never see to it, when is the best time to buy and sell, that's the reason why people loose a lot of money. The main reason that i see why investors makes major mistakes is that they fail to do research and in all cases, that is the reason they loose, be it a new investor or an old one.
That is a mistake that everyone who hits the charts without learning and either following other people's opinion to trade, or gambling their positions without the use of any indicator but the mindset that as long as they buy low and sell high, they are good.
That is how a lot of them always end up losing their funds. TA and the use of indicators are there for reasons and they are not decorations, and anyone who feels they can just do it on their own, I am really looking forward to their success stories.
