I am new to this forum and I have noted some useful value add comments.
Wonder if anyone can help me?
Is Bitcoin mining still happening or this is relevant only for new Crypto currencies ?
...
Just as other users already explain, no miners means no block confirmations, without them the network would die.
After some years, has become really difficult to mine blocks, is a task we can't do with our CPU now, but that's why people have developed more powerful miners, if you search for some you will find cheap 9Thz miners and some other more powerful.
