the blockchain.info wallet is rubbish... it supposedly uses a dynamic fee system, but it is so far out of touch with reality that it would appear that the devs at blockchain.info are either incompetent or just don't care enough to fix it. As such, your fee was way too low. The current recommended fees are much higher (and have been for a number of days now):
The fastest and cheapest transaction fee is currently 360 satoshis/byte
The current best transaction fees 240 Satoshis/byte | 0.0024 BTC/KB
I suggest you do the following:
1. Hit up the
ViaBTC TX Accelerator - submit your transaction within the first minute of a new hour or the 100 slots will be gone
2. STOP using blockchain.info wallet. It is rubbish. Go here:
https://bitcoin.org/en/choose-your-wallet pick an app from the Mobile/Desktop section.
If you insist on using blockchain.info... then make sure that you click "Advanced Send" when you are sending out a transaction. Here you can see/set the fee to be used. It still probably won't work very well, as you have no idea what the data size of your transaction is going to be, so calculating a decent fee will still be very difficult... and the "recommended" fee that Blockchain.info calculates is pretty much guaranteed to result in around 120 sats/byte...
Hence the 235683245 threads on here from people with stuck transactions with fee of 120 sats/byte...
