I searched how to kill Bitcoin on the search box and saw nothing, so I'll just start a new one.

Is it true that miners are the one responsible for every transactions?
If yes; why didn't the government of China just ban cryptocurrency mining or am I just missing something out?

If there are no transactions or maybe just less than 10 made transaction happened within 24 hours, how will the mining computer work then?, will it just go idle?What if people decided to hodle their coins, will it be unfair for the miners?
