1. So, how could I sign-in the message through blockchain.info? Is there any reference/guide as this maybe pretty hard with new blockchain wallet as I've ever read.
2. The sign-in message just byteball address without quotes, right?
Thanks for your help.
use Multibit it's much easier
Not an option for now obviously, it takes hours to move bitcoin.
Others can say ; use electrum wallet is easier, use this wallet and that wallet but not answer the questions.
if you're sending btc from blockchain.info increase your fee to 25k sats. it should move your btc within 1-2 hrs
