Attempting to read the analytical data, assess movement/the market

I'm still rather new to crypto, and I was curious to know what you more advanced traders/investors think about the current market / analytical data / etc... I attempt to read the graphs, but I know that looking at a 1 min / 15 min/hour graph that looks like an uptrend doesn't necessarily mean anything long-term. How far out do you look to try and analyze the analytics that is more likely to confirm an upswing or downswing? I have slowly been collecting ETH (and Matic) for 7-8 months now. It's a real pain living in NYS, as I'm much more limited when buying/attempting to earn interest / or even staking my ETH. Obviously, it's damn near impossible to catch a falling knife, but that is why I wanted to ask you more experienced traders about what specifics you look at before you 'buy the dip' as to not get (as) screwed buying what you thought was the dip. I want to invest a great deal more into ETH, but fire, I could really use some advice on resources/methodologies / etc... on how to properly read the market. Any help/input would be greatly appreciated. I know we're all waiting to hear what the FED comes out and says, what, if any, impact do you think their comments could have on the crypto market? I feel like so many people say go watch some youtube videos, but it's hard to trust those who are making a profit regardless by posting youtube content, making me innately distrustful of them from the start. Any advice for an ETH enthusiast who's trying his hardest but could use some advice would be greatly appreciated. What is your game plan at the current moment? Thanks in advance for ANY help/resources/advice.

Edit: For instance, I bought some more ETH at 3200, thinking that was the dip, although most of my Eth was purchased at around 2300. I want to DCA, but I want to do it when it would make the most sense, as I'm spread a little thin as it is.
