How do you ensure that you are not paying too much for a transaction, Talking about transaction fees, how many sat/byte do you use for transactions?
The two sites suggested by Charles-Tim are very helpful for you to make sure that you know how much you need to pay for each transaction.
Do you increase and decrease it depending on how quickly you want the transaction to be processed or how big or small the transactions value is?
That's right. It all depends on our needs.
Do you use a fixed amount for transactions?
In this case it also depends. I usually always add a few sat above the fixed amount of the medium rate or close to the fast rate.
For example, if the transaction is using the mobile version of the wallet as shown in the picture, then I will add 19 or 20 sat to the fixed amount (14 sat).
