Publishing a trip only gives initial credit which is upto 100. This also depend on the story , the image quality and how good you have explained the trip. Also the content should not be copied. If tripto does not find it convincing then 0 credits are added. Try editing the trip. Add more photos and describe in detail. Check out my trips.
Dear fellow traveler, it takes time (2-3 days) to your trip to get published. but in some cases it takes more, once I published a trip and it takes 21 days to published. So don't worry about it, You will receive an e-mail from Tripoto when your trip got published and how much amount of credits you awarded for your blog/trip,
