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.
