Obtain [CoinMarketCap](http://www.coinmarketcap.com) [USD price history](https://coinmarketcap.com/currencies/bitcoin/historical-data/) data for CoinMarketCap-listed cryptocurrencies in CSV format.
Use this library as a command-line script to obtain historical cryptocurrency data on the fly, or import the library to obtain cryptocurrency data for your programs.
## Installation
Download the zip file or navigate to the desired install directory and run:
```shell
$ git clone https://github.com/Alescontrela/coinmarketcap-history.git
```
To install the required dependencies, navigate into the repo and run:
```shell
$ pip install -r requirements.txt
```
## Usage
### Command Line
Among other things, this is useful for US tax reporting. If you want to know the cost basis for a trade (or for coins acquired through mining), the IRS requires you to denominate that cost basis in USD. In the case of token-for-token trades (e.g. purchasing ETH with BTC), that requires you know the USD:BTC exchange rate at the time of the trade.
Surprisingly, as of October 2017, it's not easy to get this data in a machine-readable format anywhere online.
Rather than getting the exchange rate at the exact moment of your trade, which is generally not feasible, the IRS standard (at least for similar situations w/stock) is to use the average of a stock's high and low price for the day. CoinMarketCap doesn't provide this figure, but this tool calculates this number and includes it in the output.
#### Command Line Usage
In the terminal, navigate into the repo directory and run:
```shell
$ python coinmarketcap.py <currency1> <start_date> <end_date>
```
where:
* `currency` is the (case-insensitive) name of the currency / token as displayed on CoinMarketCap, with dashes in place of spaces
* `start_date` is the beginning of the range to fetch data for in `yyyy-mm-dd` format. For example, 2017-10-01 (for 2017 October 10th)
* `end_year` is the end of the range to fetch data for in `yyyy-mm-dd` format. You may use a date in the future to obtain the latest data. Format is the same as in the start date.
Data for multiple cryptocurrencies can be obtained with:
```shell
$ python coinmarketcap.py <currency_1,currency_2,...,currency_n> <start_date> <end_date>
```
**Note:** currencies must be comma-separated, with no spaces in between.
The above information can also be found by running:
```shell
$ python coinmarketcap.py -h
```
Write outputs to a file by running:
```shell
$ coinmarketcap.py <currency> <start_date> <end_date> > <output_filename>
```
#### Command Line Examples
Collecting data for one cryptocurrency:
```shell
$ python coinmarketcap.py bitcoin 2017-01-01 2017-12-31
```
Collecting data for multiple cryptocurrencies:
```shell
$ python coinmarketcap.py bitcoin,ripple,ethereum 2017-01-01 2017-12-31
```
Writing output to a file:
```shell
$ python coinmarketcap.py bitcoin 2017-01-01 2017-12-31 > bitcoin_prices.csv
```
Writing output for multiple cryptocurrencies to a file:
```shell
$ python coinmarketcap.py bitcoin,ripple,ethereum 2017-01-01 2017-12-31 > bitcoin_ripple_ethereum_prices.csv
```
## Module
You can also use `coinmarketcap.py` as a module in other python modules to get back a pandas dataframe with a cryptocurrency's history.
First, you may need to add the path to `coinmarketcap_usd_history.py` in your `sys.path` through a command like the following:
```python
sys.path.append(<path_to_coinmarketcap_usd_history.py_parent_folder>)
```
(Alternatively, just move the `coinmarketcap_usd_history.py` file to the directory of the including module.)
Second, import the module:
```import coinmarketcap_usd_history```
Finally perform this to obtain the dataframe:
```python
df = coinmarketcap_usd_history.main(['bitcoin','2017-01-01','2017-12-31','--dataframe'])
```
If you just wish to have the CSV output returned as a string to another python module, simply omit the `'--dataframe'` parameter.
