And how accurate have TA and charts predicted the situation we're now in?
Just an addition: My brother checks no crypto-charts. He prefers Forex and gold. Does the same logic apply there too? I honestly don't know what to say or whom to address to.
I don't know s8&^ about gold but forex is far more predictable than crypto, you have dates when statements are released, you have a lot of information about who is going to raise rates by how much, you know the economic context, you know the debt of a country, the status of their economy, if you're careful with leverage and you stick with small amounts you can make some $ but once you dive in too deep you're going to get recked like in crypto by something unexpected.
As for everyone saying how crypto trading is profitable due to knowledge and experience, crypto trading seems like that because in bullish seasons everything you would trade was going up, everyone was making money, some were making money trading shitcoins, and were happy with their strategy without realizing they would have made the same by just keeping the coins. When the bear season started, trading became not so attractive anymore, because this is where you would have to actually guess the price swings, and all the "knowledge" didn't help you once.
But just like gamblers who are sticking to the story of having a "system" so do crypto traders, they claim to have a model, but in reality, is just guessing work.
Gold is an asset with less volatility, I have not traded it before, but I know the market can not be manipulated with over $10 trillions of gold market worth. I can only guess that the less volatility makes it suitable for people that are rich because using small amount of money to trade gold is not worth it and over leveraging is not advisable at all. I do not know much about it but I do know that some people prefer to just hold it which is perfect than holding money in bank.
But regardless of what a trader is using to trade, they should use the amount of money they can lose and not affect them.
Forex is good too, fundamental analyses can be more used to back technical analyses in forex, fundamental analyses in crypto is not as much as in forex just like you said it, but in reality, I have seen people that trade forex and lose great amount of money, I have seen people trading forex for years but they were not able to even buy a small car from it. Comparing forex with crypto may have more fundamental bases but trading generally is risky overall, that is why experience matters the most.
Crypto trading is more than that, but you are not wrong because we can see how people were making money in the bull run time and we can also see millions of dollars liquidated during the bear market. An experienced trader that is devoted with crypto trading, using the right coins like bitcoin, ether or litecoin and not shitcoins, they can still use technical part of analyses to make money, but they should not be greedy and using a very low leverage like 3x below for bitcoin. I prefer 1x.
