Just like fundamental analysis there's different ways to analyse, or different strategies. This also works for technical. I believe you can certainly apply technical analysis to the altcoin market, just as much as you can fundamental. Both do usually achieve different things though. Fundamental typically tracks trends, whereas technical tracks value in investment. There's usually more stability and confidence in decision making when doing technical.
Technical also suits longer term trading, whereas fundamental is short term.

Technical analysis is following the numbers without going into greater detail about the inner workings of a company, whether its should product come to fruition, and so on (read you don't have to understand the company Warren Buffett style). This is what fundamental analysis is concerned with. In other words, it is fundamental analysis (as the word itself suggests) which is more, and in fact, by far more longterm. On the other hand, with technical analysis you don't get busy with evaluating all those fundamental factors which affect business profitability in the long haul. You just pick up some TA tool and see if it works. If it doesn't, you try out something else until it does
