And maybe you could use Coinbase or Blockchain wallet, and use regular send, then the fee would be set by them, and with that fee it's guaranteed that your transaction would be confirmed fast!
This is completely and utterly untrue... blockchain.info is one of the biggest culprits at the moment of low fees... and responsible for the vast majority of "help my transaction is stuck!" threads here... their completely broken "dynamic fee" system basically just set every transaction to use 120 sats/byte... when recommended fees were 300+... 
The only thing guaranteed with binfo wallet... is you will have issues
