Technical analysis work on any trading instrument but over the years, it has proved to be less active in many ways. The fundamental analysis precede technical analysis in all areas reason is that the market is move by what people see or hear which is the news. Technical analysis involved the used of chart to forcast the future expectation of the market but you don't need that to survive trading alone, you need to be even more of fundamental like 60% and the rest of the technical should take the 40%.

Another reason technical analysis might have not been working for you is that it could be that is because the crypto market is clouded by judgement of institutional investors, and there decisions can void the market irrespective what you think and how you want it to go. For instance, the Bitcoin market has been moving in the lows of $41,800 and $42,500 as we have enter the weekend and the daily candle has turned to high selling pressure as indicated from MACD and by trend, we should slowly apprached a support of $40,000 but you and I know that Bitcoin is going to break $45000 if ETF is approved on monday and it might even go higher to the resistance of $50,000.

What you need to do right now is to mix your strategy with more Fundamental analysis than the technical you are so focus on and this can be achieve through following some real crypto news and some Youtube channels that have quick updates about bitcoin update. You should focus on bitcoin more because everything about bitcoin is surrounded by bitcoin news and information.
