I am in Latvia ( which is not supported to sell apps at android market ), so I am thinking about the best way of monetizing my app. So far I've come up with such options:

1. somehow imitate that I am from a supported country, get a bank account there, etc.

2. use PayPal for in-app purchases. The player get, say, first 10 levels for free, but then is asked to pay 0.99$ for the rest of the game.

   downsides: player might not feel comfortable entering his paypal details into an app. also android market might not really like that.

3. making the app free and get money from advertising... let's do some calculation here, say, I get 1m free downloads, each user during his playtime would see 10 banners, therefor 10m / 1000 * 0.3 = gives roughly 33k$ ( if we use adMob with their 0.3$ per 1000 impressions ). On the other hand, if we use paypal in app purchase, we need a 3% or more conversion rate to beat this... hmm...

What do you think about all this?

Thanks!

edit: from what I just read all over the net, it looks like advertisers will change their eCPM price a lot without you understanding why... while using in-app paypal purchase you can at least somehow monitor the cashflow.
