I don't know if I do it "right" but I leave a long tail and crochet over the tail first. Then the whole reason for doing the magic loop is to minimize the center hole. So after I get a few rounds in, I pull the tail to tighten the hole, then tie it to one of the backside treads (as hidden as I can make it) in a small knot w/ a drop a fabric glue in the knot, weave a little and trim.How do you secure the ring?
