What is crypto trading?

Could you please elaborate on the concept of crypto trading for those who are not well-versed in the field? Specifically, I'm interested in understanding the fundamental principles and processes involved. Is it simply buying and selling digital currencies like Bitcoin and Ethereum? Or does it involve more complex strategies and techniques? Additionally, could you discuss the risks and potential rewards of crypto trading, as well as any specific platforms or tools that traders utilize to execute their transactions? I'm curious to know how crypto trading differs from traditional financial markets and what makes it unique in today's digital economy.
