Hi. Yes, I'am Turkish. My English is not very good. In fact, both can be used in such sentences. Just as in English, sometimes the present continuous tense can be used instead of the simple present tense.
Yes, I think you are right, but I am struggeling with the following: Why could'nt I say "inanıyorsan" here, as in the other similar sentence: "Ona inaniyorsan, devam etmelisin", where inanırsan is not accepted. Can you explain that to me?
