Topic: How do miners fees work? Technical questions and confusions (Read 481 times)

Hi,

I have blockchain.info and the regular Bitcoin Wallet.  It appears that they include a 0.0001 miners fee each time.  Great!  However some of my transactions take 50 minutes to confirm so I want to add extra to the miners fees to make sure that never happens again, because that is just annoying.

I can't do that with the Bitcoin Wallet and on blockchain.info I have to click custom send to increase the miners fee.  Ok I figured that out.

What if I buy something online and I scan their QR code and they want let's say 0.123 Bitcoins.  Surely my wallet will withdraw 0.123 Bitcoins plus 0.0001 Bitcoins as a miners fee (total 0.1231 Bitcoins).  Then the seller/recipient gets 0.123 Bitcoins right?  Now what if I want that transaction to go through faster?  What if I want to give more miners fee while going this route?  Is that even possible?  Should I just not care and assume it will get there eventually and in a reasonable amount of time?

Can I change the automatic miners fee to be higher on an android app wallet?

I have seen so many discrepancies with the miners fees and values I guess this is why people use Bitpay etc.  I kept getting tripped out that my recipients were receiving different amounts of BTC when I clicked send, but realized that if I was sending a specific dollar amount that the BTC amount would fluctuate by the time it got to them.  So confusing.  Do you guys maybe know of a good article that explains nuances.
