Like the idea, passive income is always welcomed, but you can never guarantee 'a stable and guaranteed income', especially not in crypto. Sure you formulate the task as 'a stable and regular profit', but profit nonetheless.
Yes, you are right, unfortunately no one can guarantee future success in the cryptocurrency industry, because we all depend on the success of the industry as a whole. All that we can do is hope for the best and contribute to enhancing its influence on the global market through expanding the number of products built on blockchain technology and popularizing cryptocurrency among ordinary users. Our project is doing just that and this is what we are trying to achieve.
