A piece of advice:
If you don't know what a stop loss is, Bitmex is definitely NOT the right place to be. The confusion can be enormous when you add margin trading, take profit targets, and other sophisticated nuances on top of the normal trading routine.
Much better would be to start trading on a platform that doesn't offer leverage trading but does have stop losses.
Or at the very least, stick with the Bitmex Demo platform for a while until you have learned all the ins and outs of this platform.
I agree!
Don't even think of starting your trading career at BitMEX. You can check more beginner-friendly trading platforms such as Bitstamp, Coinbase or eToro. Don't use leverage trading in the beginning.
