A block contains on average 1,000 to 2,000 transactions. The average transaction only has a couple inputs and outputs. But you can make a transaction that has as many inputs and outputs as you want, which increases the size (in bytes) of the transaction. The person who spent the 80BTC on fees in this block used up about half of the space in the block, hence the high fee. It was also spread over several transactions, not a single one.</text><parent_chain><item><author>mootothemax</author><text>&lt;i&gt;the correct fee should have been approximately 2BTC.&lt;/i&gt;&lt;p&gt;At current rates isn&amp;#x27;t that a $5,000ish transaction fee?&lt;p&gt;Have I misunderstood something? That seems like a crazy amount, especially given the hype surrounding Bitcoin.</text></item></parent_chain></comment><story><title>Accidentally pay an 80BTC transaction fee?
