Please don't stay away from BTC since if you can predict BTC moves you can predict the most market is going. In fact, most of traders that I have followed what they do first is predict BTC moving after that they start to analyze the altcoin. Bitcoin waves is real.
Good Luck
Mate, if its slow mover then definitely easy to predict the window of its landing price. I think that will easily make some good cash for ya! However, I get it why are you saying that and that's because of the current market situation for the bitcoin. The case is reverse actually, bitcoin is very volatile and easily making drifts up and down by 2-5% biweekly basis, or may be more. If you find proper sweet spot to make an entry for the futures then definitely it can payback huge amount of money.
Moreover, trading in any instrument is basically same the TA and FA story. What hardens the traders life is consistency and patience breakage! If they loose any of it, the trade is gonna get messed up.
