According to TechFlow, according to OKLink data, since the fourth Bitcoin halving (as of 18:00 on April 22), nearly 60% of Bitcoin miners' income comes from transaction fees, of which the transaction fees generated on April 20 due to the popularity of runes exceeded 1,000 BTC. In this regard, OKLink Research Institute stated in its latest article that although this miner income structure based on transaction fees is not sustainable at this stage, it proves that the increase in transaction fees brought about by active Bitcoin chain activities is theoretically sufficient to generate continuous positive incentives for the miner group, thereby offsetting the negative impact of the reduction in block rewards brought about by the halving.
