Hi pornluver, Please be very careful with our Bitmex strategy. It is not Margin Lending at all, but Derivatives. We advice you to read carefully about this, and be sure to understand fully the mechanism and its consequences. Read again the Bitmex blog post from our help on Bitmex and its references. You will change your BTC into USD equivalent (short XBTUSD) and will earn funding interest only on USD equivalent. Please also monitor closely the Margin call price and leverage. Our bot will not take care of this part. You may lose your capital or earn negative interest, depending on your strategy and on the bitcoin trend.
