Well, it seems TAs are not working even anymore. Even CZ, binance CEO saud it after thia recent usdt FUD pump. He said months of good news and insights into the cryptospace couldn't trigger an uptrend and just a alse news triggered it. Seems market is moving away from predictions and we can all testify to that because this year, many predictions never worked. Some analysts even ended up reducing the target prices.
Well, one way or the other, TA has been working over the years and it will still keep working and it is not Technical analysis that is the problem of this market or what bring about speculation. TA is just for someone trying to look for patterns and trade those patterns, even in life, there are patterns, so what makes it bad, when it comes to a market. Whatever that has cause, I do not know but I would not think TA has caused any issue in this market at all.
Speculation on the other hand, is just something that is basically on its own, and market, as long as people are bidding, will always have some speculative instances. It is just the level of speculation that matters here which we all know that as far as this market is concerned, where there is no real life usage yet; speculation is a norm of the day but would not be like that forever as the market gets matured and usable in the long run.
