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?
I tried to flash back in order to recall the things that happened before in cryptoccurrency but I could get it right, I try to understand the concept that btc was very low rate in order to purchase but currently the value of btc now is know longer the value's before.
