TA is "self-fullfilling prophrecy" and that's why it works on traditional markets like Forex because everybody is using it. In the other hand, cryptocurrency field is full of geeks and not that much professional traders, so TA is not much used - not having the same effect as it has on Forex.

Tried to use TA for cryptocurrency... Maybe it can be only applied to BTC/USD because it's big, but when you look at alt-coin field, it's so wild TA has no appliance there. Graphs are so weird and you can't see that weird graphs in any of TA tutorials.
