In a bull market, I think the TA may not work at some point, it follows certain behavior as the market reacts to the sentiments but TA does work in most cases when the market goes sideways or even in the bear market.
The only psychological in trading is controlling the trader's greed which is why most advice says don't be too emotional about it. Sometimes when a trader can't wait for the right price and just keeps buying and not knowing why, he'll end up losing.
If there's anything like psychological analysis in crypto trading, it'll have to do with the trader being emotional and it might lead him to not focusing on a perticular parten, it can also lead to not knowing the right time to buy or being greedy by not knowing the right time to call it a day. Technical and fundamental analysis are however very important for every trader to understand, but the way that a trader chooses to use them is what matters, trading is hard and that is a fact, so it's good to always trade with the amount that you can afford to loose.
