I have a computer which will not used, however, it is about 4-5 years old already,
is it worth to use it to mine BTC?

If yes, how much will I expect to get in 1 month Huh

NO
you can make your computer dead

With good cooling, no but degradation is possible with 24 hours full load.

Mining with old computers is no longer a good choice. You can still hook up a USB miner or any other miner to mine but I doubt it would be profitable unless you have no electrical costs. You can also buy a raspberry pi to hook it up. Most signature campaigns do not accept low quality accounts which many people are selling right now. I would suggest that you could buy one from a trusted seller with assurance that the post history is good.
