@molfzart > why not? TA don't measure cosmic radiation, it's based on data, that comes from market emotions and good / bad news – daily people's life. Everyone is looking at the same charts, everyone is getting the same news. That's why TA more often work, than don't. TA won't show you future, but you can have peaty good guess when to enter or to leave market. And also, every TA is valid only until circumstances changes. That's why pro traders do 4 hour TA – just to know if something changed, or the same trends continues.
This fall of BTC was predicted in the beginning of march, because it's easy to draw 4 lines on chart and see support and resistance and make simple forecast – if we don't break resistance, we going to support. Resistance was around 12k, we didn't managed to do that, so naturally we go to $6.5 levels, and because there is no flood of bad news, we probably won't be going to $3.5.
That you will get from simple TA. And if you have time to learn, you can have more advanced TA, so you can short, enter and sell, etc. daily.
