This is probably the oldest and most well-known way to earn Bitcoin. It’s also probably the most appealing method for how to earn bitcoins to the newbies who don’t know any better, yet. Once upon a time this was undoubtedly the best way to get bitcoins as it was relatively easy, fast, cheap, and low-risk. By mining for Bitcoins, you can essentially make money for nothing, and a LOT of people have done exactly that. However, it’s not quite so simple these days! As with anything that has huge opportunities to cash in associated with it, things get a lot harder as time goes on and more people catch-on, and bitcoin mining is one such thing.
Banks such as JP Morgan still view cryptocurrencies as unproven and likely to drop in value. Benoit Coeure, a board member with the European Central Bank, argued in January 2018 that cryptocurrencies could prove to be a good system for cross-border payments as long as there is an understanding of how to "control these gateways between the shadow-currency universe and the regular financial system." Less than a year later, he referred to bitcoin specifically as the "evil spawn of the financial crisis," while still acknowledging the broader potential of cryptocurrencies.
It shouldn’t come as a surprise that this makes the top 10 list. Let’s not forget that Bitcoin is a form of currency, so selling goods and services is one of the best ways to earn bitcoins. Yes, you can make money selling just about any type of product or service, and accepting bitcoin as a payment method. These days, even a lot of major retailers are now taking bitcoin as one of their payment options.
Ethereum is another use-case for a blockchain that supports the Bitcoin network, and theoretically should not really compete with Bitcoin. However, the popularity of ether has pushed it into competition with all cryptocurrencies, especially from the perspective of traders. For most of its history since the mid-2015 launch, ether has been close behind bitcoin on rankings of the top cryptocurrencies by market cap. That being said, it's important to keep in mind that the ether ecosystem is much smaller than bitcoin's: as of January 2020, ether's market cap was just under $16 billion, while bitcoin's is nearly 10 times that at more than $147 billion.
