Never understood this lines but I drawed one from the sight of an optimist

That's pretty much my point too. I see a lot of posts here with screenshots of Bitcoinwisdom with randomly drawn lines but not so much explanation/detail/Actual TA behind it... Usually the lines are simply placed in a manner that supports the poster's sentiment.
I'd like to know who everyone thinks does the best TA here (or on Tradingview etc) because I don't really have time to sort the wheat from the chaff myself...
That's quite lazy (although at least honest) and short-sighted: ask that question in here, and you'll get 10 different answers. Now you're faced with the same problem: who do you trust to give you a good recommendation about who's best at TA.
That said, watch out for masterluc (posts infrequently recently) and TERA. Both are rather bearish at the moment, draw your own conclusions from that.
