Please do show us how you make a 1gb (998,000 kb) tx please, I'd be really interested to see how your pulling that off whilst still paying 0 in tx fees. The fact that your post seems to suggest a single 1gb tx I think the chain is safe in most realistic scenarios in which DigiByte can find itself in, (I have no clue why or how you'd create a 1 gb tx while paying 0 in fees).
