For me trading can be briefed into 3 steps:
1.Patience
2.Controlling greed
3.Controlling fear.
If you can follow all 3 mentioned above, you can be a successful trader.
Patience -- Wait for the right oppertunity to take a trade.
Controlling greed -- Fix up a target and close your trade whenever it hits TP or close a part position and let the other run with BE SL.
Controlling fear -- Do not get panic if trade goes against you, if it is going against you cut your loses short and wait for the next trade, keep a SL at as per your risk but do not wait to get it hit.
Looks good on paper, but it doesn't work like that in reality. We humans will always be greedy and experience fear when money is involved. How can we not? Trading isn't a fun hobby we do to enjoy. It's serious business. In order to counter our human weaknesses, we use bots that actually do what they are programmed to do, and that in the best possible way.
It shouldn't come as a surprise that algorithmic trading activity in the crypto market has exploded this year. Staring all day at price tickers to manually day trade is an utter waste of time.
