What are the two 2 sources of data?

Excuse me, could you please clarify what you mean by "the two sources of data"? Are you referring to the sources of information or data points that are commonly used in the cryptocurrency and finance industry? If so, there are typically two main sources of data that are relied upon: market data and fundamental data. Market data includes things like price movements, trading volume, and order book information, which can provide insights into the current sentiment and momentum of a particular cryptocurrency or asset. Fundamental data, on the other hand, refers to information about the underlying asset or company, such as financial statements, news events, and regulatory developments, which can help investors make informed decisions about the long-term potential of an investment. Is this what you were asking about?
