As Jonathan puts it, “Digital currencies aren’t going anywhere… Whether that’s Bitcoin, or Stablecoins, or central bank digital currencies (CBDC) – their time is coming, as we see the move away from cash to cards and fast, contactless payments. The UK Government even recently announced their plans to make the UK a global cryptoasset technology hub.”
Blockchain and Cryptocurrency Explained is a beginner-level certificate course that takes approximately nine hours to complete. If you’re interested in starting a career in FinTech, you might benefit from earning a credential. The course is offered by the University of Michigan and explains how blockchain works and the strengths and weaknesses of cryptocurrency.

In the early days of Bitcoin, desktop computers with ordinary CPUs dominated Bitcoin mining. However, they began taking a long time to discover the solution on the blockchain network as the algorithm’s difficulty level increased with time. According to some estimates, it would have taken “several hundred thousand years on average” using CPUs to find a valid block at the early 2015 difficulty level.
To be able to mine with some chance for success, you’ll need to invest in one of the top graphics processing units (GPUs, often called video cards) for your computer or an application-specific integrated circuit (ASIC). Capable GPUs can range in price from about $1,000 to $2,000; ASICs can cost much more, into the tens of thousands of dollars.
You’ll also notice the difficulty level for this block. The Bitcoin network aims to produce one block every 10 minutes or so. The system is designed to evaluate and adjust the mining difficulty every 2,016 blocks or roughly every two weeks (based on the number of participants). This doesn’t always result in a block time of 10 minutes, but it’s close.
Bitcoin has been adjusted by introducing upgrades and accepting input from layers that do much of the work off-chain, but it still has issues with scalability. When making adjustments, blockchain is surrounded by three central concerns: decentralization, security, and scalability. With current technology, one cannot be changed without affecting another. For example, if the Bitcoin blockchain were altered so that it could scale more effectively, it would likely decrease security and increase centralization.
As the difficulty and complexity of Bitcoin mining has increased, the computing power required has also gone up. Bitcoin mining consumes about 166.75 terawatt-hours of electricity each year, more than most countries, according to the Cambridge index. You’d need nine years’ worth of the typical U.S. household’s electricity to mine just one bitcoin as of August 2021.
