Title basically... oh and how long does this bot need to getto like 10k gold and around 4-5 golden portraits ?
Well, gold is 140g per day minimum, so do the math. >_> Portraits, well, do you want to farm them 24/7, or do you want to do 30 wins per day to avoid looking like a bot? In saying that if you choose 30 wins per day, do the math. Both answers, do the math.
Why would you need an option to skip tutorial? It's really fast to do and you only have to do it once. About your other questions, to get 10k gold, you need to do 30 wins per day for 72 days maximum. Depending on the quest you get every day, it might be faster than that. For 5 golden portraits, it would require 2500 wins. So if you do 30 wins a day, it would take 83 days. Good luck!
