In my opinion, this holds cryptocurrencies from being a usable and reliable method for everyday transaction use.
What is your view on this?
It seems that your complaint is more about speculation causing volatility than against TA itself. I agree that speculation and volatility are problems, but I take a long term view. I use Bitcoin now as much as I can, regardless of the price, and I will continue to do so in the future. All of these price fluctuations are ultimately just minor bumps in the road in the face of a long term adoption juggernaut. I am not concerned.
BTW, I agree. TA is nothing more than astrology for traders.
