There was a time when anyone with a graphics card–or even just a CPU–could mine some Bitcoin and turn a profit.
But why did Bitcoin go from being an easy money maker to something few can afford to mine?

Not that you have to print Bitcoin, of course. How Bitcoin Is Mined Bitcoin, like seemingly every other technology these days, is based on the blockchain. In Bitcoin’s case, these blocks are used as transaction ledgers that make sure every exchange of the cryptocurrency is legitimate.

Doing all that math requires some computational resources.
