actually i am fine with the fee because so far i see that when i am sending the bitcoin, the fees is not more than 0.0005 btc but some exchanger apply the fee 0.0005btc. but with this thread, i know that the fee now is 15k satoshi, thank you for mocacinno for share the links.
Bittrex and Yobit both apply 50k satoshi fee, also if the minimum is 15k as mocacinno shared. Yobit raised to 50k a few month ago, bittrex was already at 50k satoshi minimum fee since more time.
If you look at Poloniex, probably they are the biggest exchange out there, and they are still making a minimum btc transaction fee of 10k satoshi.... below the minimum... i don't know how long will this last, but today they are very cheap in transaction fees.
Don't know if there are better fees exchange sites.
Just to set the record straight guys, i never said the minimum fee was 15k satoshi's... Somebody in this thread probably looked at the link, and calculated that for their transaction 15k satoshi's was the minimum fee in order to have a decent chance of getting their transaction confirmed in the timespan they wanted.
The fee is not something you pay to an exchange. The fee is given to the miner so he has an incentive to add your transaction to a block. If you cheap out on the fee, you have a chance your transaction will never be added to a block, hence remains unconfirmed and eventually gets kicked out of the mempool (gets forgotten).
It is possible some scrupulous exchanges add an extra fee on top of the miner fee and keep this one, altough i don't know any exchange that does this, it's a possiblity.
