Sorry for my eng. I just started learning it.
My way - int cpi (0.25$ payout ±) + plugrush, popads, adcash, etc etc.
What i can try? Do some blackhat landing pages, because all affiliates use it. I use adplexity, some other spy tools and hand search. I cant find any 1 affiliate with good volume and whitehat landing pages. Only 2 guys with .apk my offer, but i know 1 network with this offers, its +80% payout and only for 1k+/day guys.
I wanna launch all countries (almost all) with low cost for each. Find potential and optimize it (black/white lists; test/splittest landing pages; tablet/mobile; browser).
I start from LATAM. And this my fail. I launch 19 countries and my offer accept only 7 from 19
Little fail = -300$.
My stat without this fail:
Spend: 124$
Revenue: 38$
Profit: -86$.
ROI: -69%.
Not bad, but all countries got little traffic, its main problem.
I try optimize this, but now my main point - arabic or others big countries.
My background: in 2014 xxx-xxxx/day with sweepstakes. But last 2 months cant do any xx-xxx$/day campaign. Yep, its not a problem. I was persistent. I try find good mentor, but now its big problem in contrast 2010-2013, because so much newbie who doesnt want to work.
My money: 10k$ in my card. And 10k$ credit line 
Target: xxx$/day for start with CPI. And xxxx$/day after ofc.
Parallel i fight with Facebook (got accs, selfmade cloak and some other stuff), but it another story.
New day, new stat:
Spend: 65,3$
Revenue: 43,3$
Profit: -22$
ROI: -34%
Play with targeting, with landing pages, if i see little traffic try increase 2-3x bid (just mb my bid so low for good volume). More volume, more good placement, white list = $$, my logic. Doesnt work in 3x sources, little work in 1 another source.
Spend: 61$
Revenue: 72$
Profit: 11$
ROI: 18%
My countries so small for volume. I try 10+ traffic sources, doesnt help. Next stage - countries with volume.
Nice! Keep up the good work man, you are doing great.
Hit me up on skype so we can brainstorm a bit more about your campaigns - would love to help you grow
Spend: 41$
Revenue: 68$
Profit: 27$
ROI: 66%
Stop all campaigns with low traffic and with 1-3$ profit/day with no hope about volume. Because many campaigns = a lot of time for optimization + voluume price plans not much friendly for volume 
Next step: 3 big country + 3 big traffic source. Full focus on it.
Red thru this, looking forward for your updates 
throw cpi with popup+redirect in trash. Start working with Facebook + some blackhat offers. Find good offer and do 7-8k$ for first week, but my offer die. And now cant find any another good. Mb anyone can help me in PM? What i can break with Facebook.
About Facebook - have no problem with traffic, can spend 500-1000$/day or more. Help me my friends, i can be good ref or good friend in IM 
Did you completely switched over to FB? How's that working out?
