So to answer your questions, i was very sleepy on my last reply. Sorry!
I have not limit myself to Swedish speaking area. I just started that way, and i have build up the reputation and marketing the current websites, last month they running quite good by them self so I am ready to take a new challenge. Right now I building a online casino that will be have Bitcoin and more Crypto as Currency. I know we have bitztars and stakes as the "biggest" right now. But they can improve alot, thats why i focus that area right now.
And yes. I agree, if i have English I can get more customers, but two websites is offering loans to pepole living in Sweden. So English would not help there anyway. Loan affiliate is very very good income. So no, you need to be Swedish citizen to take a loan in Sweden.
The casino site is for Swedish people to. BUT its possible to make a casino site for thw whole world. But as i said, I aint there yet.
But now I am ready to start a new project, you need to look what is profitable in your country.

Yes, I checked your website and use Google translate to understand more from there. I was surprised at how much online loan services you have in Sweden.
But maybe you are right, now your websites are strictly dedicated to targeting specific people in a specific area which significantly affects the usefulness and relevance for your visitors.
I suggest you (if you don't until now) to check BestChange service
