Ok good so last question.

When I log onto coinpayments . Under recent transactions it shows a payment to the recipient I was sending it to. The recipient uses coinpayments to process their sales transactions. It shows .04689000 btc under recent transactions. How come this amount is less? Do I still owe them more btc even though in the link I posted it shows the full amount of .05591646 btc was transferred?

Please look at this link. Would the person receiving the payment get .05591646 BTC?
Yes, if the person is in control of the wallet address 3Lo5H7DLBTs4stnk1i6xMCQf7KHe7QswYF

When you invest in Blockchain, you have to deal with crypto money processing fees. This is nothing new to you as you are on stock market stock exchanges, as well as for using third party services.

However, due to the decentralized nature of the crypto currencies, you must pay using a crypto network. The network must be encouraged to verify all operations in the block chain and you are paying a fee.

Therefore, there are three types of transaction fees when dealing with cryptographic currencies;

Fees traded on exchanges
Transaction costs
Wallet fees

My wallet is a Trezor. In the drop down box it gives you a list to choose from regarding the transaction speed. Normal, fast, slow etc. Next to each speed rating there is an amount next to it in sat/B. I dont know what the B stands for. So I picked normal. That was 646 sat/b. I was sending .05591000 and it ended up sending .0593984 automatically.
The amount sent includes the miner fee.
If you're sending 1BTC, with a standard transaction size of 226 bytes (one input and 2 outputs) with the fee you paid, 646sats/byte, which amounts to 0.00145996 BTC, the total your wallet will send is 1BTC + the fee of 0.00145996BTC = 1.00145996BTC

 

So if I send too much. I will get change back?
No. If you overpay fees you won't get "change" back.
This is why you should confirm your transaction before sending.

How do I know how much to add? They didn't tell me an amount.
Your wallet already showed you slow, normal and fast.
It calculates the recommended fee and you can usually trust it, but if you don't trust your wallet's estimation then use https://bitcoinfees.21.co to find out the current recommend fee for quick confirmation.

the b stands for Byte.
when you send a bitcoin transaction the fee you pay depends on how big your transaction is in bytes. in other words you pay for the  data that you are sending and want to be included in the blockchain, that  data is your transaction. normally it is 226 bytes. but if you have received multiple payments and now want to spend them all, your transaction size will be bigger.

(edit: i may have made some calculation errors calculating the fees you paid)
you are paying 0.00348840BTC with 646 sat/b fee, so your transaction size was 540 bytes. which means you are spending more than 1 transaction output (received multiple payments).

as for amount you sent, you shouldn't look at the total sent. you should instead check the transaction to see how much you sent to the address they gave you and how much went to your change address.

your transaction should look something like this:
https://blockchain.info/tx/6930ca7e882fc53b722e14efc1cd29789ae12d7146c9a0978ac6e838a752590b?show_adv=true
you can see it is making a 0.1729BTC payment to the first address and getting 0.00102696 BTC back as change. and the fee is 0.00535181BTC

So if I send too much. I will get change back?

Basically I made a purchase in BTC on a website. The invoice had the purchase amount on it. Then in a note it said to make sure you send enough BTC to cover the transaction fees.

This was the first time I have ever sent BTC.

My wallet is a Trezor. In the drop down box it gives you a list to choose from regarding the transaction speed. Normal, fast, slow etc. Next to each speed rating there is an amount next to it in sat/B. I dont know what the B stands for. So I picked normal. That was 646 sat/b. I was sending .05591000 and it ended up sending .0593984 automatically.

 Why does the website remind you to include enough for the transaction fee? Don't you automatically pay the fee just to send it from your wallet? Did I need to add something extra?How do I know how much to add? They didn't tell me an amount. The website uses coinpayments to conduct the sales transactions. Is there a fee to receive it also that I needed to include?
