I kind of disagree with you, it is true most of shitcoins and memecoins are just a vehicle for people in the cryptocurrency market to gamble their money away, though when comes to Bitcoin, Ethereum and other blue chip alternative currencies, there are factors which definitely affect their value in the market, which can be predictible and used by traders to make a profit off those factors... being the most obvious one of them (in the case of Bitcoin) the programmed halving and the amount of hash rate there is in the network, obviously, after halvings there is a tendency for Bitcoin to start to raise in value.
As a miner I can tell you that hashrate has nothing to do with price, price is the one dictating the hashrate, higher prices higher revenues higher hashrate as miners buy more gear to make more profits, if hashrate would do anything to the price then it would be pretty simple, we all would just buy gear and the price would go up, well, not that simple!
Second, no, bitcoin didn't act like any blue chip company at all, one clear example is how it behaves when it touches round prices, you always have a back and forth as people take profits and so on, like now with 100k, like it was with 100 and 10 000, this thing doesn't happen for companies, but most importantly, there is no pattern in it, you don't have anything to actually trade based on other than your guts of it going up, there is no number from which to start your TA other that past experience, and we all know how that went.
Trading cryptos is gambling, it's just the ego of traders that denies it.
