Blockchain.com payments Need some assistance if I need to stop and take my losses. I had Bitcoin mined and the earned profits. I paid the commission fee and the profit was moved to blockchain.com. They requested a payment of $3500 because it’s a new wallet. Unfortunately I didn’t pay it timely due to purchase limits only cash app and coinbase accounts. I paid the $3500. But then they said Bec of the delay i had to pay an additional $2000. Yes I paid that and now they are saying I need to pay $3500 again within 3-4 days.  Is this normal process?  Please help!
Yes, this is a common process used by scammers. It ends up in you paying them lots to withdraw your money that has never been yours without receiving even 1 cent from them.
Don't write to them but seek help from your local authorities.
