I believe that the human mind is more powerful than any rsi or fibonacci tool in analysing the implication of price action. In fact, the human mind is the worlds most superlative pattern recognition machine, therefore, were able to pick up on the simple fact that there are cycles in everything the weather, ocean waves, and altcoins.
PATTERN
A consistent, characteristic form, style, or method, as:
a. A composite of traits or features characteristic of an individual or a group: one's pattern of behaviour
Just like we are able to predict the actions or movements of friends and family based on the behaviour that they have exhibited in the past, It is in this same way that you can also anticipate the movement of any altcoin simply by assessing its behaviour in the past.
In Crypto, most traders never get past the starting gate because they dont use good selection criteria. They dont know what to look for to find the most optimal trading opportunities which is why they consistently buy into and sell out of positions at the wrong time and end up losing money. They arent tuned into the bigger picture.
You dont need an assortment of smoke screens or voodoo priests to consistently win in Crypto. All you need is an ounce of common sense, patience and the ability to accurately exploit price patterns.
Most Coins behave uniquely when compared with others. This is due to the psychology of the people who are trading them. Different Coins have different batches of traders behind them, and so they behave differently. One Coin may have a habit of trending, whilst another coin will have a habit of staying range bound.
Its amazing how complex but simple this whole thing is, it really is like a game and the way you describe it as "behavior" is right on point. Its sorta like a group of traders make their play and then another group responds and then this creates a sort of pattern like you mention
