I think each person will have his or her own judgment on Technical Analysis. Technical analysis will give us the basic knowledge when we do transactions but that is not all of the factors that make up this cryptocurrency market. This market is still small and manipulated so we have to choose to follow our own way of trading, unlike anyone who can get profit.
Because of that manipulation, the market is so hard to predict even if you are using TA. Well, I do both of this i only trade with the top coins who are strong enough fundamentally, and of course trade with the trend that is base on my studies. Its hard but we have to do this so we can be more effecient in the market.
