This is nothing new OP.It's Martingale and now a days it doesn't work.Almost all casino's are designed this way to detect a martingale easily.you are saying to use this will small amount.I would say using this method would be a complete waste of time.Gambling is gambling because there are no fixed strategies otherwise it won't be called gambling.Got it OP? 
Casinos detecting martingale? The heck you talking about, why would casinos give a shit about martingale? Of course they all have limits but not because martingale is a good strategy. Just-dice registered 32 losses in a row using martingale, they obviously don't care about it if they allow 32 plays of it.
