So block rewards become half every four years or so. At some point in the future, they might be just a fraction of a bitcoin like for example – 0.01 bitcoin or something.
At that point in time why would a bitcoin miner use all the resources that are required to mine bitcoin if the rewards are so low?
And if they stop mining, won't that mean there won't be any more transactions on bitcoin?
The only reason I can think of as to why they would continue to mine is a 0.01 btc reward would be quite valuable.
What do you guys think?
