This high-level API client provides open access to cryptocurrency market data, sentiment indicators, and interactive charting tools. 
  The data is sourced from major cryptocurrency exchanges via 'curl' and returned in 'xts'-format. The data comes in open, high, low, and close (OHLC) format with flexible granularity, ranging from seconds to months. 
  This flexibility makes it ideal for developing and backtesting trading strategies or conducting detailed market analysis.

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.
