People make money from weird bitcoin businesses. So basically there is nothing like this bitcoin business is better than other weird business. Because everyone can make millions literally from bitcoin business.
Do not feel biased towards bitcoin industry because many kind of business works only if you make it work, so as usual, a business is just a model if it won’t operate without the entrepreneur. It’s just like a car, it won’t move without the driver and how fast you rich your destination depends on the skill of the driver, not the car model.
