I just want to make right steps without wasting time, energy and money.
But you doing trading of altcoins, right?
Yes, but very, very small amounts. I don't bother with TA, I just presume anything on Poloniex will eventually pump and sit there until it does. I've never made a loss because they're utterly shameless and will literally pump anything. I don't know how long that can last though.
My preference is to get in on the ground floor with something new. There are enough coins being given away for free. If you buy in with small amounts when they're tiny then you might get lucky, if they fail it doesn't really matter.
It's seems, that you just using other strategy to do trading, not choosing to do TA, but trying new coins and waiting for the big pump.

Every person chose how they do trading, what strategy and plan to follow.
I am very new to trading stuff, so it's very interested to know more about it and about all the strategies and trading plans/methods.
But I still believe that good and proper TA minimise the risk and maximise the chance of correct prediction.
