What is the Cryptoradar?

BISON's Cryptoradar is a sentiment based on artificial intelligence that analyzes more than two million tweets from the crypto community daily in real time for the investor. It filters them for relevance and prepares them visually. In a nutshell, you can imagine a barometer of opinions under sentiment. BISON's Cryptoradar thus shows you which tradable cryptocurrencies are currently being discussed hotly - without you having to follow thousands of tweets or messages.

How does the Cryptoradar work?

In essence, BISON's Cryptoradar is based on the approach of machine learning, a form of artificial intelligence. Imagine the following: every day, an algorithm automatically evaluates over two million crypto-based tweets. But it cannot do this without the input of the BISON team. The algorithm was "trained" over several years using training data to understand the semantics of messages and to classify tweets into one of three categories - positive, neutral or negative. In addition, each day the algorithm selects tweets that it cannot rate with 100% certainty. The algorithm then forwards these messages to our BISON team of experts who help the algorithm and tell it how to classify the messages. The algorithm remembers this information and abstracts it again in the next case. In the first step, two million tweets are checked daily for their relevance to the respective cryptocurrency. Tweets that do not add any value to the analysis (because they are either spam or similar) are filtered out. The remaining 250,000 tweets are classified by the BISON algorithm into one of the three classification categories. The result is BISON's Cryptoradar, which shows you the sentiment regarding the cryptocurrencies available in the BISON app.

What is Sentiment/Buzz?

In short, sentiment represents the opinion barometer in the crypto community and the buzz represents the number of people who spread their opinion about the respective cryptocurrency via Twitter. The better the average opinion about the cryptocurrency - more positive tweets - the further to the right the respective icon is placed in the Cryptoradar. The stronger the buzz of the cryptocurrency - larger number of tweets - the higher the icon is displayed. This simple representation allows you to see relatively quickly and easily what the current mood is towards Bitcoin, Litecoin, Ripple (XRP), or Ethereum.

Cryptocurrencies are digital currencies with a cryptographically secured and decentralized payment system. In contrast to conventional money, such as dollars or euros, a cryptocurrency is only available in digital form. The technical implementation of digital currencies is based on so-called "blockchains". Cryptocurrencies are seen as a new asset class and are therefore exposed to greater volatility than conventional money.

What are Bitcoin, Ethereum, Litecoin, and Ripple (XRP)?

Bitcoin (BTC)

Bitcoin was released in 2009 and is the first and most important cryptocurrency. The inventor is a certain "Satoshi Nakamoto", whose real identity is unknown. Bitcoin consists of a monetary unit and a payment system. The digital currency (BTC) is created and managed in a global decentralized computer network using special software. The global system is based on a decentralized database in which all transactions are recorded in the form of a blockchain. Bitcoin gained worldwide attention due to its value growth in 2017.

More information:


Litecoin (LTC)

Litecoin (LTC) is a global and decentralized payment network comparable to the Bitcoin network. The main differences between Litecoin and Bitcoin lie in the area of technology. The transaction speed, the maximum offer of the respective coins, and the algorithm used should be emphasized.

More information:

Ripple (XRP)

Ripple (XRP) is an open-source protocol based on a public database. The Ripple network supports all major currencies. The XRP was released in 2012 and, unlike Bitcoin, is not based on the blockchain, nor can the coin be mined.

More information:


Ethereum (ETH)

Ether (ETH) is the internal means of payment for transaction processing for the global platform Ethereum. The Ethereum platform is used for Distributed Apps and enables the creation, execution and management of Smart Contracts.
