Apr 11, · The oldest free market think tank in the United States, the Foundation for Economic Education (FEE) has announced the (c)3 educational foundation now accepts bitcoin cash (BCH) for donations. The libertarian organization promotes sound economic theory, publishes books and articles regularly on the benefits of a laissez-faire attitude, and hosts lectures and conferences that aim. Trading fees are based on a rolling day total of AUD trading volume, across all AUD trades. Trading volume is calculated every hour. The relevant trading fee is applied when an order is created. The trading fee across crypto-only pairs (LTC-BTC, ETH-BTC, XRP-BTC) is a flat-rate maker % & taker %. These trades do not count towards AUD.

In addition, demand varies according to certain patterns, with perhaps the most recognizable being the weekly cycle where fees increase during weekdays and decrease on the weekend:. These variations in supply and demand create a market for block space that allows users to make a trade-off between confirmation time and cost. Users with high time requirements may pay a higher than average transaction fee to be confirmed quickly, while users under less time pressure can save money by being prepared to wait longer for either a natural but unpredictable increase in supply or a somewhat predictable decrease in demand.
It is envisioned that over time the cumulative effect of collecting transaction fees will allow those creating new blocks to "earn" more bitcoins than will be mined from new bitcoins created by the new block itself. This is also an incentive to keep trying to create new blocks as the creation of new bitcoins from the mining activity goes towards zero in the future.
Perhaps the most important factor affecting how fast a transaction gets confirmed is its fee rate often spelled feerate.
This section describes why feerates are important and how to calculate a transaction's feerate. Bitcoin transaction vary in size for a variety of reasons. We can easily visualize that by drawing four transactions side-by-side based on their size length with each of our examples larger than the previous one:.
This method of illustrating length makes it easy to also visualize an example maximum block size limit that constrains how much transaction data a miner can add to an individual block:. Since Bitcoin only allows whole transactions to be added to a particular block, at least one of the transactions in the example above can't be added to the next block.
So how does a miner select which transactions to include? There's no required selection method called policy and no known way to make any particular policy required, but one strategy popular among miners is for each individual miner to attempt to maximize the amount of fee income they can collect from the transactions they include in their blocks.
We can add a visualization of available fees to our previous illustration by keeping the length of each transaction the same but making the area of the transaction equal to its fee. This makes the height of each transaction equal to the fee divided by the size, which is called the feerate:. Although long wide transactions may contain more total fee, the high-feerate tall transactions are the most profitable to mine because their area is greatest compared to the amount of space length they take up in a block.
For example, compare transaction B to transaction D in the illustration above. This means that miners attempting to maximize fee income can get good results by simply sorting by feerate and including as many transactions as possible in a block:.
Because only complete transactions can be added to a block, sometimes as in the example above the inability to include the incomplete transaction near the end of the block frees up space for one or more smaller and lower-feerate transactions, so when a block gets near full, a profit-maximizing miner will often ignore all remaining transactions that are too large to fit and include the smaller transactions that do fit still in highest-feerate order :. Excluding some rare and rarely-significant edge cases, the feerate sorting described above maximizes miner revenue for any given block size as long as none of the transactions depend on any of the other transactions being included in the same block see the next section, feerates for dependent transactions, for more information about that.
To calculate the feerate for your transaction, take the fee the transaction pays and divide that by the size of the transaction currently based on weight units or vbytes but no longer based on bytes.
For example, if a transaction pays a fee of 2, nanobitcoins and is vbytes in size, its feerate is 2, divided by , which is 10 nanobitcoins per vbyte this happens to be the minimum fee Bitcoin Core Wallet will pay by default. When comparing to the feerate between several transactions, ensure that the units used for all of the measurements are the same. For example, some tools calculate size in weight units and others use vbytes; some tools also display fees in a variety of denominations.
Bitcoin transactions can depend on the inclusion of other transactions in the same block, which complicates the feerate-based transaction selection described above.
This section describes the rules of that dependency system, how miners can maximize revenue while managing those dependencies, and how bitcoin spenders can use the dependency system to effectively increase the feerate of unconfirmed transactions.
Each transaction in a block has a sequential order, one transaction after another. Each block in the block chain also has a sequential order, one block after another. This means that there's a single sequential order to every transaction in the best block chain. One of Bitcoin's consensus rules is that the transaction where you receive bitcoins must appear earlier in this sequence than the transaction where you spend those bitcoins.
For example, if Alice pays Bob in transaction A and Bob uses those same bitcoins to pay Charlie in transaction B, transaction A must appear earlier in the sequence of transactions than transaction B. Often this is easy to accomplish because transaction A appears in an earlier block than transaction B:. But if transaction A and B both appear in the same block, the rule still applies: transaction A must appear earlier in the block than transaction B.
This complicates the task of maximizing fee revenue for miners. Normally, miners would prefer to simply sort transactions by feerate as described in the feerate section above. But if both transaction A and B are unconfirmed, the miner cannot include B earlier in the block than A even if B pays a higher feerate. This can make sorting by feerate alone less profitable than expected, so a more complex algorithm is needed.
Happily, it's only slightly more complex. For example, consider the following four transactions that are similar to those analyzed in the preceding feerate section:. To maximize revenue, miners need a way to compare groups of related transactions to each other as well as to individual transactions that have no unconfirmed dependencies.
To do that, every transaction available for inclusion in the next block has its feerate calculated for it and all of its unconfirmed ancestors. In the example, this means that transaction B is now considered as a combination of transaction B plus transaction A:. We'll deal with this complication in a moment. These transaction groups are then sorted in feerate order as described in the previous feerate section:. Any individual transaction that appears twice or more in the sorted list has its redundant copies removed.
Finally, we see if we can squeeze in some smaller transactions into the end of the block to avoid wasting space as described in the previous feerate section. In this case, we can't, so no changes are made. Except for some edge cases that are rare and rarely have a significant impact on revenue, this simple and efficient transaction sorting algorithm maximizes miner feerate revenue after factoring in transaction dependencies. Note: to ensure the algorithm runs quickly, implementations such as Bitcoin Core limit the maximum number of related transactions that will be collected together for consideration as one group.
As of Bitcoin Core 0. For spenders, miner use of transaction grouping means that if you're waiting for an unconfirmed transaction that pays too low a feerate e. Wallets that explicitly support this feature often call it child pays for parent CPFP because the child transaction B helps pay for the parent transaction A.
