I want to send 0,01 BTC from blockchain.info to Poloniex. What is the minimum fee I can use? This site bitcoinfees.21.co says that it should be enough to use 21 sat/b and get transaction in 9 hours. But I've heard that there is a minimum total sat size (around 5460) to prevent dust transfers. Please advice.
I used 1sat/byte up to 5 byte/ sat for my micro payment transactions but it would take 1 to 7 days for 3 confirmations. I would suggest to check customize few option at different times during the day and prefer to do transaction at time when fees are at minimum due to low load of transactions.
