I can't prove to you that it works.
I can tell you that I don't just do a charting based analysis, you can watch my youtube videos (same name) for my in-depth looks. For example, I called out Bitconnect as a scam and I talked extensively about regulatory risks.
Charts do not "just work in a stable market." I stated in very clearly, ver batim, without any knowledge of news driven events "if BTC falls below $12650 it will be a bloodbath," and, sure enough, I was proven correct.
The charts' first and foremost task is to figure out areas of support and resistance! I am tired but you have a good synopsis here of why I disagree with your assertion.
I am not your financial adviser.
Do not over-trade.
A price target is not "price will touch this number and then rocket down again," it's just a guess that at some point in the near future, price will at least TOUCH that number, even if only to go 5x higher.
In my opinion - again - my opinion and bias - all cryptocurrencies will retrace between 20-35% of their losses in the next 5-7 days. Do with that what you will. I think market cap will touch $700bn again very soon, but I don't know what will happen after that.
Watch the news on South Korea.
