This high-level API client offers a streamlined access to public cryptocurrency market data and sentiment indicators. It features OHLC-V (Open, High, Low, Close, Volume) that comes
  with granularity ranging from seconds to months and essential sentiment indicators to develop and backtest trading strategies, or conduct detailed market analysis. By interacting directly with
  the major cryptocurrency exchanges this package ensures a reliable, and stable, flow of market information, eliminating the need for complex, low-level API interactions or webcrawlers.

Generate random numbers from the Cryptographically Secure Pseudorandom 
    Number Generator (CSPRNG) provided by the underlying operating system.  
    System CSPRNGs are seeded internally by the OS with entropy it gathers
    from the system hardware. The following system functions are used:
    arc4random_buf() on macOS and BSD; BCryptgenRandom() on Windows; 
    Sys_getrandom() on Linux.

Allows you to connect to data sources across the 
        crypto ecosystem. This data can enable a range of activity such as 
        portfolio tracking, programmatic trading, or industry analysis. The 
        package is described in French (2024) <https://github.com/TrevorFrench/cryptotrackr/wiki>.

Providing data to quickly visualize and analyze data from several cryptocurrencies.

An API wrapper for 'Cryptowatch' to get prices and other information (e.g., volume, trades, order books, bid and ask prices, live quotes, and more) about cryptocurrencies and crypto exchanges. See <https://docs.cryptowat.ch/rest-api> for a detailed documentation.

Performs cryptographic randomness tests on a sequence of random
    integers or bits. Included tests are greatest common divisor, birthday spacings,
    book stack, adaptive chi-square, topological binary, and three random walk
    tests (Ryabko and Monarev, 2005) <doi:10.1016/j.jspi.2004.02.010>. Tests except greatest common divisor and birthday spacings are not
    covered by standard test suites. In addition to the chi-square goodness-of-fit
    test, results of Anderson-Darling, Kolmogorov-Smirnov, and Jarque-Bera tests are
    also generated by some of the cryptographic randomness tests.
