My understanding is that to be able to mine a meaningful amount of crypto, you need to set up a farm, buy hundreds of graphics cards, buy electricity cheaply, etc, but that it's got infinitely harder in the last few years. This isn't my field, so do your own research.
Mining crypto (BTC) is now more expensive per coin than the value per coin. Why not invest in BTC instead? With a fixed supply of 21 million coins, Bitcoin provides a reliable store of value, positioning it as a compelling option for retirement investors seeking a hedge against monetary debasement. 2025 is highly likley to prove BTC as a great asset in a bull market.
A friend of mine figured out his online business path by leaning into what he already had years of hands-on experience with—construction equipment. Instead of chasing random “hot” niches, he started sharing practical tips, troubleshooting guides, and even safety know-hows around excavator use and maintenance. At first, it was just for a small community he was in, but over time it built him a solid following and turned into a steady source of income. The big takeaway was that when you work in a space you actually understand, it’s much easier to produce valuable content and gain trust, which makes monetizing far more straightforward.
That's true very often - IF there is demand for the niche. If there's nobody out there who wants the information, product, or service that you offer you have nothing to monetize. Another profitable way of monetizing information is by reviewing products and preparing reports based on those reviews. Success relies on you actually getting the product and using it so you know what you're talking about when you create your review. And, of course, your review must be completely impartial (something that's difficult to pull off, especially if at the end of your review you're offering that product as an affiliate sale). And again, you'll need to make sure there is demand for the products that you review.
