Method 33. Cryptocurrency Mining
This is another way to earn passive income. With a mining rig, you can earn Bitcoin. The amount you earn depends on how powerful your mining rig is. Even though it’ll take a lot of electricity, your ROI will come out to be much greater.
Some people even mine with solar power and cool their rigs by leaving it in cold weather.
There are even mining farms in China. With the slow adoption of cryptocurrencies, there’s no doubt that the Bitcoin value will increase over time.
