no, the techniques are exactly the same. but you should know that "chart analysis" is not exactly science and it is not fool proof. in other words you don't predict anything with your analysis, you just make some guesses about most possible things that can happen. and it doesn't really have to happen.

"emotion" has nothing to do with it. the crypto market in general is small and because of that it is easy to manipulate. there are altcoins that you can simply pump with as small amount as 1BTC!
