What happens if you reset your iPhone a lot?

I have already reset my iPhone 5c 3 times, and I want to reset it again. The reason why I keep resetting it is because I'm running out of space too often and I just want to keep starting clean, it seems that's it gets a little slower after each time I reset it. Should resetting my iPhone be a problem? It is a new software considering the 5c is a newer phone. This is kind of a stupid question but I really need an answer.

You don't need to ever reset it. Offload videos and pictures to computer, and for best speed make sure you close apps when not using them, don't just leave them all open.

Just try deleting pictures or unnecessary apps you don't want-- it can open up more space instead of reseting it

I don't think resetting will cause speed issues so their shouldn't be a problem as for the speed just close all the apps and it should do it
