Transactions fees

Knowing how Bitcoin transaction fees work is an essential part of knowing how to buy Bitcoin. In most cases, Bitcoin miners prioritize transactions that have higher fees in the order book when considering them for processing. This means that paying a higher fee can result in faster confirmation of your transaction.

Transaction fees are based on two factors: the size of the transaction and how much space it takes up on the Bitcoin blockchain (also known as the data size). Fees fluctuate according to network conditions, but generally run between 0-10%.

Here’s what you need to know about Bitcoin transaction fees:

  1. Transaction size is measured in bytes and can increase or decrease depending on the complexity of sender’s wallet address or whether a multisig address setup is used.
  2. Although some wallets will automatically set an optimal fee, it’s best practice to double check your chosen fee prior to sending out any bitcoins so you know approximately how long it will take for your transaction to get confirmed by miners.
  3. Generally speaking, lower priority transactions (those with smaller fees) get included in blocks first (so they enter “the mempool” quickly), but may take longer to confirm due to their lower payout size. High priority transactions (which pay larger fees) require more time before they’re included in blocks because they yield higher miner payments overall.
  4. To minimize total costs incurred from submitting multiple transactions at once, always try consolidating them into one big one instead of sending several small ones separately since overall rates are significantly cheaper for large multi-output sizes versus several separate inputs.

How to avoid paying high Bitcoin transaction fees

Paying high fees for a cryptocurrency transaction can have a negative impact on the return of your investment. To help ensure that you are not paying more than you need to, there are various strategies available to minimize the amount charged for Bitcoin transactions.

One of the most common strategies is to carry out multiple transactions at once, as many wallets and exchanges can reduce or eliminate fees when they are combined into one payment. Additionally, some exchanges have an option for “maker” orders and “taker” orders which can help avoid paying high fees if you choose wisely – with “maker” trades incurring lower fees than “taker” trades.

Finally, it’s worth noting that many wallets allow users to set custom fee values when sending bitcoin transactions – meaning that it’s possible to assign priority transaction speeds based on how urgently those transfers need processing. Although setting custom fee values may result in higher costs in certain cases they do provide an effective way of avoiding excessively high processing delays due to congested networks or unexpected price hikes during periods of intense market activity (such as during Bitcoin ‘halting’ events).


In conclusion, understanding Bitcoin transaction fees is an important part of trading in cryptocurrency. As a trader, it’s important to know the basics of how block size and mining operations will affect the cost of your transactions. Additionally, researching different wallet services and their fee structures may make it possible to keep more of your profits from successful trades.
