I owned two including the one I have now, and the handle is fine, don't worry at all. If you want, put the moka on the very side to avoid heat on the handle.
Other than that, the tip I saw years ago was to leave the cap open when you put on fire, and close it when the coffee comes out. To be true, I tested cup and no cap, and it was the same. Yet I still do open Cup.
It's called Moka pot.
