Once we have determined to become a trader, we need to determine that we will inevitably fail in the early days and in the learning process. If we cannot accept that then we should not engage in trading or investing in cryptocurrencies. Because investing is inherently risky, no one can guarantee that simply entering the market will automatically make a profit. This is a financial market where we will use money to make money, not a job market that uses labor to make money. If you cannot accept losses and do not want to lose money, then investing or trading will not be suitable for you.
Accepting loss even before trading is definitely vital but its not a good look. We can't just tell people "you are going to lose money" and expect them to be happy about it, that could scare away a lot of paper hands and we may not end up with some good traders. This is why we should be focusing on how we could make it work a lot better, and how can we do that?
We could end up making sure that people know that losing is actually not that bad. How can we do that? To show them that each loss is a lesson they can get better from with proof, like examples. If you do that then you are going to be fine and your returns will increase. So just focus on the losses as learning curve, the money you spend on becoming a better trader.
