That is because the people on here that claim they are using technical analysis just take charts and draw random lines to match a theory to sound like they know wtf they are doing, or they give such absurd ranges (170-330 price target!) so they can't be wrong.
In theory why would TA apply to btc?  None of the theories were created about btc.  Would you follow a recipe a recipe for brownies while making cookies? 

Some of the people aren't full of shit, but 90 percent of the self proclaimed btc analyst are.
