Most traders always think that acquiring the skill of trading will reduce the losses
It won't. Acquiring the skill means that you are accepting the fact that anything can happen in the market. That your wins and losses are perfectly painted in probabilities. Having the skill in trading is knowing when to take the risk and when not to. Because losses are normal part of the game in trading. It's like taxes or transaction cost that need to be payed to be in the game.
We can make money in trading or crypto investment if we have the knowledge and what to do that will keep giving us the money to keep going. Winning and lossing is a common thing in the market and everyone also faces it to the core.
There are so many mistakes we might be making as a crypto trader and we need to always work on it if we want to be making consistent profits in the market. Disciplinary measures are one of the things that have kept many good traders in the market for many years without having to quit due to negative results.
