• The reduction in Bitcoin block rewards by half as a result of the halving has doubled the investment required by miners to break even.
• Following the halving event, Bitcoin's price decline has further exacerbated the challenges faced by miners, leading to a 72% decrease in hash rate.
• Despite the decreased block rewards, the rising transaction fees provide a potential source of revenue for sustaining Bitcoin mining operations.

After the completion of the Bitcoin halving, miners are now faced with the challenge of operating with reduced block rewards. The recent reduction has cut incentives from 6.25 BTC to 3.125 BTC per block, meaning miners must increase their investment efforts to maintain profitability.

In addition to the decrease in block rewards, the decline in Bitcoin's price has worsened the situation for miners, making it harder for them to cover their costs effectively.

The rise in mining costs following the halving has added to the industry's difficulties, particularly with profit margins already on the decline.

However, despite these challenges, there is hope in the form of transaction fees, which have significantly increased post-halving. This trend may help alleviate some of the financial pressures on miners and ensure the sustainability of Bitcoin mining operations.
