Bitcoin mining verifies transactions on the block chain. Eventually people might stop doing this once the mining reward becomes too small or once mining is over 100+ years from now.
Would advanced mining (quantum) solve this making only a few miners necessary to verify transactions?
What are your thoughts?
Your understanding of how bitcoin works is deeply flawed.
I suggest taking some time to learn a bit more before you start to panic about what is going to happen in the future.
Please explain us what's wrong with his question.
