Take note that you don't needs to analyze the market as a Bitcoin investor, just buy once your discretionary income is available because the price of Bitcoin now is still very cheap comparing to how much it might be in ten to twenty years time from now, so why analyzing?
And secondly, their is nothing as a short term investor, it's either you are a long term investor or a trader that buys with the intention of selling for minimal gains in a very short time interval, so in my own opinion, those people that buy and sold their Bitcoin just because it appreciate in value are not investors, they are traders that sold for minimal gains.
Finally, when it comes to investment in Bitcoin, the best way to go about it is to think only long term because the way Bitcoin is wired, you can only reap the full dividend of your investment when you buy and hold for a very long period of time, not minimal gains that wouldn't have any significant impact on your financial status.
Different people see it differently, but yeah, generally, BTC is seen as the true store of value to be hodled for a long time, 4-5 years at minimal, to see good results, accumulating little by little.
Other coins cannot be used for the same logic simply because they are not as stable.
Analyzing before buying is not for investors who are on DCA method or the ones that are planing to get on the strategy, there's absolutely no need for it because they're supposed to be taking funds periodically from their discretionary funds to accumulate no matter what the price of Bitcoin is at the time. It helps to understand that Bitcoin is a store of value and your Bitcoin is not lost when it dips, that it has the potentials to recover and rally so there is absolutely nothing to worry about speculating price before buying. Analysis is for traders and gamblers who wants to predict what price will be on the short term to know when it's profitable for them to offload but for a long term investor there is nothing to analyze about, except perhaps to speculate for the sake of it to know how the market is trending nothing more.
