with us the client keep control of the funds.
Uhm... no. The client gives the funds to Bitmex AND gives an API key to you. And you keep lying that there is no risk. Not cool.
Still no DYOR?
Api key is limited to only order creation. you can find the risk involved a few posts above.
I doubt there's a more legit a transparent service on Bitcointalk. But i get it, we are new and doubts are legit.
Time will tell the truth, like always!
