What m ore can you ask for? Are there some better models that need to be plugged in that are not merely noise? Yeah we here all kinds of bullshit theories and we even have guys coming in here and rolling their own models while failing/refusing to account for the most convincing and credible of the currently BTC price prediction models. Sure bring up some other factors, and we will see if those factors mean anything to the long term models or might need to be tweaked into the models, but the vast majority of the time, a lot of these various other factors are not worthy of much beyond some kind of short-term phenomena, noise or insignificant aberrations of the data.
I also think with you that those who work with Bitcoin first think that they have achieved a lot of success, but most of the time they work there even if they apply the complete formula of trading in cryptocurrency, but only a little bit in the case of Bitcoin. Although it is much less in number or percentage, if you apply the theory of trading very carefully 50% -60% is useful the rest is not very useful.
But if I were to talk about a few more things would say that many traders here can't accept losses because of the leverage.
