I think the essence of the article is how difficult it is for many to invest properly in the crypto market, so they do nothing but follow the indications and recommendations of supposed gurus with all the risks that this implies.
And it is certainly true, because I think that the futility of technical analysis in the crypto market has become clear to most (in fact, many reject the possibility that the TA is useful in any market) so they base their decisions on mere hunches and emotional impulses.
If we are an expert in trading, we always have our TA's and basically apply our own strategies. It never work alone and even more profitable if we don't have such effective strategies. TA's is just a guide or market speculation base on the chart or any tool they used to track market trend but we know how volatile we are that is why it needs strategies that will help by then,
