So the yahoo finance forex api more data that can be offloaded from the unspent transaction records to the rest of the blockchain, the better. Moving forward There are still many wallets and bitcoin services that have not implemented dynamic fees. The market for block space, receiving the fees from hundreds of transactions (0.44 BTC).

This section describes why feerates are important and how to calculate a transaction's feerate. As the number of blocks received in a period of time varies, so does the effective maximum block size. To prevent "penny-flooding" denial-of-service attacks on the network, the reference implementation caps the number of free transactions it will relay to other nodes to (by default) 15 thousand bytes per minute. It also offers a two-factor identification. Im concerned by a couple potential scenarios that could drive fee rates up faster than necessary: Poorly coded dynamic fee algorithms could create a feedback loop that drives the fee rate up with no ceiling as transactions continue.

This spells trouble for any developers who are writing fee estimate algorithms because now there are opaque fee markets that are invisible to the rest of the world. Wallet developers should add safety mechanisms such as sanity check thresholds at the micro level and circuit breakers at the macro level to prevent users from shooting themselves in the foot. One recent development that hasnt received much attention despite the fact that it has the potential to affect the fee market is the development of secondary miner fee markets.
