Investors wanting to be a part of Bitcoin’s history spent 37.7 BTC (worth $2.4 million) in fees alone to nab their share of limited space on the Bitcoin block, which triggered the fourth halving event, reducing them to 3.125 BTC for every block mined, until the next halving reduces them even further. The block included 3,050 transactions, meaning the average user paid a little under $800.
