Re: What happens if bitcoin mining stops or becomes too expensive?
Whether it's renewable energy or non-renewable energy, you will lose energy. If you consume energy and lose money while mining, it's natural not to mine. If mining stops, Bitcoin will dominate the market with the same amount of supply as it has. However, the current price of Bitcoin will not remain the same in the future, and if this price remains, mining companies will go bankrupt and stop mining. If the big mining companies stop mining Bitcoin, then there will definitely be a severe impact on the market.
In 2024, the Bitcoin halving block reward was 3.125, but if you calculate it, the block reward in 2080 will be 0.00019073. If the price of Bitcoin does not increase, the big mining companies will go bankrupt and they will close their companies and say goodbye forever.
It is so true that over time, years, Bitcoin halvings and market cycles, there will be less bitcoins in block subsidy every halving (it will be halved after each Bitcoin halving). This causes less bitcoin subsidy for Bitcoin miners in every block and it results in more time of mining and earning a same bitcoin amount.
This topic is insightful about it.
