The way the reasons were aligned nicely in OP would make you think that the reason why most traders loose rather than win is that isn't. In hindsight, it's not. I've recently started reading "Trading in the zone" by Mark Douglas and one of my biggest takeaways is the explanations about why someone of the best technical or price action traders end up with more losers than winners.

I bump myself into a telegram group of over 10,000 subscribers, where signal is being dropped but this is what they do, they look for a project that is in the dip and very low in price, they buy millions of that coin and keep in their wallet after that they will come to the group and tell everybody to buy this coin that the coin will pump in price.
And everybody will start buying, whereby causing a high demand of the coin as well as causing the price to go up and they will sell their own coin and make a whole lot of money then the price will drop back.
Well, that my friend, is one of the oldest pump and dump schemes that has been in crypto for as long as I can remember. These days, it's mostly influencers buying some shitcoin and then shilling it heavily on CT as the next multiple x. Mostly a 100x.
