Greetings my friend @simonnwigwe,

It is great to see your participation in the Steemit Crypto Academy Contest for week 3, focusing on understanding crypto trading. You have provided a clear explanation of what trading is and how it applies to crypto currency. You also mention the importance of having basic knowledge, such as understanding market trends, risk management, and technical analysis in order to be a successful trader.

One statement I would like to highlight is "crypto trading can be very rewarding and at the same time it can be very risky." It is important to keep in mind that crypto markets are highly volatile and it is essential to have a solid trading strategy to minimize risk and maximize profit. In your post, you also mention the different types of exchanges, centralized and decentralized, and their role in crypto trading.

In terms of building your own crypto trading strategy, it is important to have a clear understanding of your own risk tolerance and to constantly educate yourself on market trends and developments. Additionally, it is important to have a plan for entering and exiting trades and to stick to that plan. Diversifying your portfolio and having stop loss orders in place can also help to manage risk.

Overall, your post provides valuable insights and information for those interested in understanding and participating in crypto trading. Keep up the great work, my friend.
