I’m not the expert, but in my opinion it takes too much time. I also was trying to achieve it, but I wasted so much time for nothing. It became boring for me and I stopped.
it’s much better and already approved instead trying to achieve 35 level and understand that all this is a bullshit. In my opinion games can’t provide some profitable offers because of their strategy and structure, so my advice is to leave this idea as soon as you can and think about real earnings.
