I will also add that from a purely technical standpoint...in reading these charts...a lot of these coins (especially the bigger ones) seem to behave, for the most part, as a technical trader would expect. bouncing off MA's , support/resistance levels, stochastics, etc etc. All other variables aside...that is good to see.
For example..the daily chart of BTC doesnt look very good at all. 2 cycles of lower highs and bouncing off 12.5k support level (on binance) several times (descending wedge)...now its broken under that support on high volume.... and the 2 failed breakout attempts of ETH over last week if looking at 6hr chart.... now 20% lower ....
again, just from a technical standpoint...these things to seem to behave in a somewhat predictable fashion
Regarding on using Technical tools on crypto trading I can say that sometime they do might work specially on making some support and resistance level which as a trader on this field would really be helpful for you because you can assume that price would really go into that way but not anytime to give you assurance because this cryptocurrency market do involve with emotions on some time which either those walls that we predicted that to hard to breakout sometimes its being eaten up easily once emotions would really be on the involvement.
