First off the house edge isn’t the percentage. You are betting under 50, that’s a 49% odds bet. The house edge is the payout. Your making a 49% bet but making 2.00x.

Second, how does your “never lose” strategy save you when you get 11 loses in a row? Which will happen. I’m fact you will eventually get 20+ loses in a row wiping 1500 steem away.

You are just explaining the martingale strategy which most everyone already knows.
