It's true, cryptocurrencies are not the only way to make us a lot of money, to make us financially free. Many people are still living rich life without cryptocurrency. We need cryptocurrencies because we are willing to take risks to get rich quickly, but many people don't want to admit this fact.
Sometimes you don't need to have talent, you just need patience, effort, and hard work, you can also build your own business or start a business in any field you think has potential. Without those things, whether investing in bitcoin or going abroad to work, we will never succeed.
I think the difference is that it's global, I prefer crypto because it can make me rich and it is global, I can find a guy who has a product in japan, a digital thing lets say, even a pdf, and I can find a buyer in USA and sell that, then another at Germany, then another at Egypt then another at Nigeria, then another at Russia and so forth.
As you can see it's such an easy thing and the payment would only have to be via crypto, which takes a minute to use and it's gone. I can do that all day everyday. Sales alone is such a great way of making money in the crypto world. Start a digital agency, do all social media, coding/development, design and everything else like SEO and SEM etc, you do not have to know it all, you just need to sell that service, if you can sell, you can find someone who takes crypto that does these.
