if i want to send 1500$ BTC then how much network Fee should i use to make BTC confirmation fast?
Over 65k satoshi if you want to get a confirmation less than 10 minutes.
Over 260satoshis/byte.
No one can determine the proper fees for a specific transaction like this $1,500 in bitcoin, unless they see how much the size of the inputs and outputs data. Hence, saying 'pay (A) amount of bitcoin as fees to get faster confirmation' is not valid. It solely and only depends on the data size, not the amount of money transacted, nor the wallet's 'fixed/recommended' fees (as it seems to be broken somehow).
