They are now asking for $100USD (can only be paid in bitcoin) to reactivate your account to get access, I don't know why they won't just let you pay with what is already in your account.
It is cause they do not have it. They already scammed you out of it and spent that already, and probably also sold your data which you submitted to whoever was interested, so be careful with the log in details you used there which are linked to other platforms.
What they are doing now is a follow up scam.
Say goodbye to your 1 BTC and learn your lessons. If you give in to that $100 reactivation fee, then you haven't learned your lessons yet. Do not pay. 1 BTC is enough loss; don't make it bigger.
According to the OP they had spent a significant amount of the 1
BTC and lost 0.038
BTC to the website. Still a significant amount though and more than enough loss.
