Scam? Or No?

I won some form of giveaway for the website bitexcoinx.com that says I now have 0.41 bitcoin. On the website my balance does in fact say I have that much, and it seems like an okay website at first glance. Couldn’t find anything online explicitly saying that it is untrustworthy, although it is pretty unheard of. To withdraw the bitcoin it says I have, it has told me i need to make a “wallet-wallet verification” by depositing .01 bitcoin or more into my account. This is in the terms of service and it claims to be for security, but I don’t know how to feel about it. Does anyone else know anything or have any experience with the website?
