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?
I guess TA does not work because this is very new market . Once everybody had understood crypto then I guess we will not see so much volatility in market. Currently market is more on sentiments than on fundamentals.
