Question regarding the viability of bitcoin in the long term. From my understanding, the security of bitcoin comes from miners who verify the blockchain. What happens when there is so much halving that the reward for mining bitcoin is extremely low and the cost of verifying the blockchain for the miners exceeds the reward of their bitcoin?
If it weren't for the miners earn lots of money from transaction fees, then there would occur some problems I think. As long as the balance between the money that they earn (from fees etc.) and mining reward is protected, there will be no big deal for a long time. Besides, Bitcoin has been in the market for more than 10 years. It can be seen easily that Bitcoin has a strong system.
