One thing I noticed is that sentiments shift nowadays faster than people change their underpants, like literally in the meme 1-2 days there is wall of green positivity and hopium, or wall of red negativity and fire and doomsday calls, hence some days i just stay away from social media, it's sickening, maybe im wrong but i dont think sentiments were shifting as fast 3 years ago. It's very mental.
From what i noticed in trading one must go by himself through all of it to really learn and have conviction about things, in other words, one needs to experience things on his own skin, otherwhise just listening to what other TA people say or trying to learn from the charts history is not working the same way as real experience.
Of course some learn quicker than others, i just speak about my own experience, i havent learned about taking profits for example on the top of previous bullmarket, i needed to experience things going further down to see how things work, then on the bottom first part i havent realized how liquidity moves in the market... so yes, i learn as i go and try to not make the same mistake twice.
I think all people in crypto that have been here for a while are interconnected in some ways, this is still small space, if i go here on street asking people about crypto, 99% has no idea what it is, we are early.
