Update:
I just added my Admob to Appodeal, like I explained before: This is how I do it now:
Tier 1 & some Tier 2 countries = Admob
Tier 2, Tier 3 + High risk countries = FAN & Unity Ads
What are high-risk countries? Those countries where my competition is from mainly. In my case it is: Mostly Thailand, Pakistan, India, Bangladesh
The app is not available in those countries anyway.
And here are some insights for you guys. This is ONE app I uploaded three weeks ago. I was driving targeted traffic through social media and paid ads (adwords)
Here are the WORLDWIDE earnings in the last 7 days. Interstitials and Banners:

Here are the earnings from ONLY EUROPE + NORTH AMERICA:

$21 eCPM. 95% of the earnings are just from those two continents.
Now you can think by yourself: Is it actually worth it to risk your app and AdMob account for Tier 3 countries? In my opinion, no. Just imagine this: Earnings $1 per day from Thailand or India and having a high risk of getting reported or click bombed, then limited for "invalid traffic".
So yes, make sure you targeting Tier 1 high paying countries.
Now let me give you one more insight into my Adwords account:

What can you see here? I target only those Tier 1 countries for app downloads.
My daily budget: 5€
Conversions = App installs
Costs per install average = 0.07€ so around $0.085
btw. important to note: The CPI costs depend on your niche, the conversation rate, etc. don't think just because I pay 0.08$ per install you will only pay this as well. It really depends.
I will double the daily budget now and then compare it to the FAN earnings.
