How do we never regret a trade again when we lose money, miss a cryptocurrency pumping, and sell our Bitcoin or altcoins early on Coinbase, Bittrex, Bitstamp, or Poloniex? The trick is realizing that as long as we are playing any game in life, losing is certain and winning happens more often
Well I disagree in thinking of trading as a game but you're right that losing is a certainty and all you have to hope is that your gains outweigh your losses. Remember that you are not omniscient and so can't always do everything perfectly.
