How To Learn About Bitcoin, Cryptocurrencies And Blockchain For Free

Bitcoin may or may not be the currency of the future, but cryptocurrencies and blockchain technology appear to be here to stay. Touted for its security, scalability, and decentralized structure, blockchain is likely to grow more important over the next few decades. It is increasingly used in a wide variety of industries, including but not limited to financial services, the automotive industry, healthcare, insurance, and law. Six of Forbes’ top 50 Fintech companies for 2020 are in blockchain. Governments have started to use blockchain technology to safeguard sensitive information and public records, and major banks have created their own cryptocurrencies and blockchain-based digital coins. Blockchain will likely play a prominent role in the widespread adoption of the Internet of Things, as it can help enhance security and resolve scalability issues. Some analysts even believe it could replace the traditional internet.

And yet, there is so much confusion around cryptocurrencies and blockchain technology more generally. Writer and designer Adam Greenfield, for example, referred to blockchain as the first technology that is “fundamentally difficult for otherwise intelligent and highly capable people to understand.” 

As crypto and blockchain grow in importance, it is crucial for people in all walks of life to get a grasp on the technology. Fortunately, there are a number of reliable online courses and resources from internationally-recognized universities and major producers of blockchain technology that will teach you all you need to know about blockchain, whether you are a computer scientist, an entrepreneur, or simply interested in learning about the technology … and they’re available for free.
