Any Help! Confused to start selling on Amazon Turkey or Amazon USA!

Amazon Turkey is new, it was launched in 2018, has little or no historical data, tools like Jungle Scout doesn't support it, I didn't find a tool that has data for/or support Amazon Turkey. I prefer to start with Amazon Turkey Marketplace as I am living there and could grow locally from there. But now I am confused.

I allocated a budget of $2000 to start Amazon business, I have local suppliers and I can source from China as well.

I attended three courses on Selling on Amazon and Product Research and Selection, I got my LLC professional account set on Amazon Turkey, launched two products FBM from local manufacturers, from three weeks, no sales until now. I expect that, no problem, I am not complaining here even this is not my exact subject. What I mean I took serious steps.

In the last two weeks, I was trying to implement what i learned specifically on product research and product selection. the problem that I cant guess what can work in Amazon Turkey. I tried many methods like:
- Guess the demand and no of product sales from the number of reviews. Then I found that not all reviews from Turkey. some are from Germany (mostly), some from other European countries.
- Find Tool that support Amazon Turkey marketplace. No data.
- Track Amazon product pages traffic, not practical, useful and risky.

Now my question:
Shall I invest on Amazon USA or Amazon Turkey. Any help will be appreciated!

Thanks in Advance
