There is a lot of talk about the “mining death spiral” of Bitcoin, where it is no longer profitable for many miners to keep contributing their resources to the ecosystem = decline of hashrate = decline of price. Ari Paul explains that miners will have to uneconomically mine for ~2 weeks to reduce difficulty level to eliminate the problem.

Bitcoin just had it’s second largest drop in mining difficulty in history at -15.1%. This also makes the capital cost of a 51% attack significantly cheaper at around a range of $10 million. Not all are in agreement that Bitcoin is in a mining death spiral though: Opinion piece by Arjun Balaji of The Block.
