:)A new BTC contract exchange recommended by a friend
https://www.bityard.comSince I seldom conduct contract transactions, I would like to ask you some questions.
1. Is the contract trading margin donated by the exchange useful?
2. Experienced GUYS help me check if this exchange is good?
3. Is there anything I need to pay attention to if I join the fund?
thank you!

First of all you inserted a reference likk there, which you can remove or moderators will delete your post
That exchange is not popular so it's very risky. I would stay away unless someone already withdrawal funds there.
Try to withdraw a small amount before sending a big amount.
