A good trading strategy is important, but what traders need to succeed is not an absolute strategy that gives 100% winning. A 60% winning strategy is okay if you can work on your trading psychology and money/risk management. As simple as the two are, they've reshaped my trading results for good.
People buy course for that amount because they think that the people selling the course will actually put their real strategy in the course forgetting that most people would not give your their secret but will keep giving you hope that if you follow their guidance that you will become successful as them but in reality, they either do not have any strategy to sell or what they will be telling you is something that you already know. People are just hopeless and if you check out those buying this course, alot of them, this is not the first course that they have bought on trading. Most traders do not have a good trading strategy but what they are doing is just copying strategy that they think are the best but they are not. Alot of people are getting deceived regularly because of this trading strategy.
This is the honest truth but many of us that are traders are not still aware of this or just trying to mix different strategies together whether it's going to be profitable. I don't blame many traders that are found of buying all these strategies that are being sold by popular traders with the hope that the strategy is going to make them money perhaps after studying and practicing for few weeks.
If you are found of buying strategies from big traders in the market for the seek of making more profits then you must be ready to keep buying more and complaining about their ineffectiveness. Every traders must be ready to learn how to trade the crypto market thoroughly without always depending on buying strategies to make money on the market.
