I want to write software that predicts the value of Bitcoin in USD. I have Python with the following libraries:
- numpy
- pandas
Where do I start?

You can start by gathering and analysing Bitcoin historical data using the Pandas library. You can use the Yahoo Finance API to import the data into a Panda's data frame, which you can then use to perform statistical analysis. After analysing the data, you can then use Machine Learning algorithms such as Linear Regression or Support Vector Machines to build a model that can be used to predict future values. Finally, you can use the SciPy library to optimize the model and validate its accuracy.

Here's an example of how to import data using the Yahoo Finance API into a Pandas dataframe:

import pandas as pd
import numpy as np

# Define the ticker symbol and the desired start and end dates
ticker = "BTC-USD"
start_date = "2010-07-17"
end_date = "2022-07-17"

# Use the Yahoo Finance API to import the data into a Pandas dataframe
df = pd.DataFrame(pd.read_html("https://finance.yahoo.com/quote/BTC-USD/history?p=BTC-USD", parse_dates=True)[0])

# Clean the data by removing unneeded columns and setting the date column as the index
df.drop(columns=['Open', 'High', 'Low', 'Adj Close*', 'Volume'], inplace=True)
df.set_index('Date', inplace=True)

# Filter the data by the desired start and end dates
df = df[(df.index >= start_date) & (df.index <= end_date)]

In this example, the read_html method of the Pandas library is used to extract the data from the Yahoo Finance API and store it in a Pandas dataframe. The parse_dates argument is set to True to ensure that the date column is automatically converted to a datetime data type. The data is then cleaned by removing unneeded columns and setting the date column as the index. Finally, the data is filtered by the desired start and end dates.
