Everyone will have a different opportunity. there will be those who win and some will lose. things like this are things that must be accepted by every trader. when they make a successful decision it will make a profit and when a trader makes a wrong decision then it will make a loss of assets he has.
It's pretty normal because it's a game of prediction, and you cannot make good prediction all the time.
You make bad prediction you loss but you strive to make it right the next time, it's about improving your strategy until you make a good one that gives profit. Every trader has different effort put in their work, some just smart enough, so we will never have the same results.
