Is this Scam

Hello, i want to ask something.
So, here is my situation.
I use Tifa Technology Company Limited.
They give me an offer.
Because i'm a new user, they give me bonus $3.888 but I need to deposit $38.888.
They give me 7 days to complete the task. If I can't complete the task, they will freeze my money.
Is this a scam or what[3f]
It hard to complete the task, coz it was a lot of money.
What should I do now[3f] I want my money back.
