You just got scammed, as there is nothing like mining for someone to get profit and I don't know who introduce you to such scam , you did what you suppose did in the first instance first last, by posting here what you pass through, instead of you asking first in this forum and let people tell you if you are right or not but now is drug after headache gone.
Don't be too anxious to have money in crypto step by step will it all, so I will advice to jearn from that and never give anyone yr password or private key to your wallet even if is yr brother as any money gone is bye gone.
