I need some PPD informations ! :)

Hi BHW people! So I joined fileice this summer and so far I've made 430$ mostly with one racing game. Now this niche died, I've been lazy for 3 months and want to start back again. I'm from Romania, 300$ / month would be higher than my mothers income... So for that 300$ I need to make 10$/ day. I know to work with PPD only with the youtube method. I can make Visual Basic programs, design in photoshop, a little bit of HTML and CSS. If I stick with youtube should I make a website where I have all my niches and a youtube channel for all the niches? Or should I make always new channels and websites for every niches. These are my questions for now, thank you! And excuse me for my english !
