But why not expect profit? If the platform can quickly become popular, then profits to investors will flow like a river. The question of promotion and advertising.
But still it takes time to promote the project. To support the platform we need expenses + advertising costs. So the first time will not be easy. But in the future, such projects are probably profitable investments.
The first few months or half of the year will be one expenses. Even if the project is mega interesting, it will not be able to be popular the next day ... this is the law of marketing. Therefore, you need to be patient and do not require return on your investment in the first month of the platform.
