While I do agree that technical analysis play a big role in trading success but there are also other things we should put into partners like fundamental, learning stop loss, resistance, etc.

But I do have acquintances who are doing some trading without the use of technical analysis. They're just doing some buying low and selling high. Waiting for bitcoin and other coin to decrease in price and then buy again. They are just following the hype and go with the flow. Just as simple as that and they are still profiting.
