I have heard some persons day that crypto does not obey TA, I have had points where TA failed and no prevailing fundamental, personally I feel TA in crypto is 50 :50. At some points it may give a good clue of next market direction at other points it is totally the opposite
People will always say whatever they want to say as long as they never tend to have a plan. For those in this category, they tend to always believe that technical analysis should always give you a 100% on point direction to where the market tends. People need to understand that in a market, what we do is educated gambling.
Without a strategy, then in this case you are really gambling without knowing exactly what you are doing. It is this reason why the risks are there, but the ability to manage those risks, with great plan and strategy is where technical analysis comes in, but I guess some people would just not understand.
