In this article I will show you how to get the price of cryptocurrencies like Bitcoin in real-time using Python.

What is bitcoin and who created it ?

Bitcoin is a digital currency and a payment system invented by an unknown group or person by the name Satoshi Nakamoto , who published the invention in 2008 and released it as open source software in 2009. It is the first decentralized digital currency, meaning the system works without a single administrator or central bank, you can use them in every country, your account cannot be frozen, and there are no prerequisites or limits .

Bitcoins are transferred directly from person to person, also known as peer to peer. The cryptographic transactions are verified by a network of people and recorded in a public distributed ledger called the block chain . Note that once a payment is made it can’t be reversed, and if you lose your wallet, you lose your bitcoins.

How much is one bitcoin worth ?

Bitcoin is very volatile, the price of one bitcoin is liable to change rapidly and unpredictably. Earlier in January 2017 one bitcoin was equivalent to $985 USD. If you had invested $100 USD in 2010, you would be worth about $72 million USD as of (12/21/2017).

YouTube video of the program


The first thing that I like to do before writing logic in my code is to put a description of what the program is about.

#Description: Get the current price of Bitcoin

Next, I will import the request library.

#Import the requests library
import requests

Now let’s store the URL of the ticker, to get the .json file of the cryptocurrencies. This link is the API from
Update: The API URL is no longer working for the free version :(


Let’s create a function to get the latest crypto currency price for a specific ‘crypto’ like Bitcoin, Litecoin or Ethereum.

def get_latest_crypto_price(crypto):

response = requests.get(TICKER_API_URL+crypto)
response_json = response.json()

return float(response_json[0]['price_usd'])

Test the function to see if it returns the current price of the crypto currency.

Create a main function to get the current price of the crypto currency, and print any price change when the API updates.

def main():

last_price = -1

while True:

crypto = 'bitcoin'
price = get_latest_crypto_price(crypto)

if price != last_price:
print('Bitcoin price: ',price)
last_price = price

Last but not least, we will run the main function.

You can easily get the price of litecoin, ethereum and some other crypto currencies simply by replacing the bitcoin string in this program with the cryptocurrencies of your choice !

Conclusion and Resources

That is it, you are done creating your program to get the current price of cryptocurrencies !

Again, if you want, you can watch and listen to me explain all of the code in my YouTube video.
