Bitcoin mining is when “miners” use powerful computers to add new records of Bitcoin transactions to the Bitcoin blockchain. The job of Bitcoin miners is to put transactions into sequence, in order onto the Bitcoin blockchain.

How is Bitcoin different from traditional money?

Traditional currencies are usually issued by governments. Bitcoin is a peer-to-peer monetary system that is not controlled by a central authority.

Traditional currencies have a physical version, such as coins or notes (although this is fast disappearing). Bitcoin, on the other hand, is a digital currency, with no physical version.

Traditional currencies are printed by the government, and these governments can print more money whenever they feel like it. It is hard to know, therefore, how much money is actually in circulation. Bitcoin, on the other hand, has a fixed limited supply of 21 million Bitcoin. So the amount in circulation can’t be manipulated to get a desired outcome by anyone.

What happens if you invest €50 in Bitcoin today?

It is important to say that before you start reading this section, no one can know what will happen in the future to any cryptocurrency price for certain. We can take educated guesses, but that’s all it is: A guess.
