But to more specific, there will be a time when all bitcoin would have been mined, during the time, will the time miners will be confirming transaction reduce from 10 minutes to 1s or a time lesser than a second. The reason is that the whole block reward scenerio will not be a reason at the time not to reduce the time for bitcoin transaction confirmation.
I do not know how bitcoin network will work at that time, but I think it can happen, it will make scalability issue to totally ans finally be solved at the time.
What is your opinion?
According to me, only those miners will continue mining who are interested to earn bitcoins out of the transaction fees.
Not many will be interested in this since LN will probably be well established and people will be making transactions on the second layer.
Very few transactions will be done on the bitcoin blockchain. This will decrease the number of miners and hence the difficulty will reduce.
Since the block rewards will be vanished very few miners will remain active and continue to receive bitcoins from transaction fees.
This will stabilize the network a lot I guess.
