Thanks for the snappy response LoyceV!
A couple of questions.
1. I do have surplus btc in the wallet, is it an easy process to do CPFP? Is my blockchain Web wallet capable / can you recommend a rookie guide perhaps? I wouldn't mind getting it confirmed prior to your estimation if it's fairly easy and risk free
2. You say chances are it'll confirm on Sunday, almost a week from sending point. I'll assume it's your familiarity with current traffic, but what makes you know this?
Side note I'll be checking out the electrum wallet after this pain transaction is sorted.
