In my opinion TA doesnt work for crypto currencies in general. I did a lot of TA in 2017 and followed a lot of well known traders at Twitter etc. None of them (and neither me) was able to predict anything based on TA, the market was way too volatile and news driven back then.
But TA is definitly nothing for newbies, you would get rekt in no matter of time.
Since you used the TA , I will like to know that how accurate you find it for stock markets?
In classic markets such as stocks / oil etc. the TA works to a certain extent in my opinion. But I'm not sure if it works because it works, or if there are a lot of bots that act on specific patterns and TA works because of that. In my opinion, the latter applies more. Man simply tends to see patterns even if there are none.
