I've just started to promote my business. There is not much money for advertising and buying traffic, so I chose the minimum conditions for myself, I invest $200 per month, I started on European push. Of course, in the future I plan to increase these costs and add to evadav pushes and native. So far I'm happy with everything. Too bad that the line of credit is only available at higher costs, or I could climb faster. So far I've been working more slowly, gradually increasing my turnover.
