Choosing a site that is proven to be fair is one key to this very strategy as well as having a great capital and also contentment and discipline,
Even how legit the site is, that strategy or I can't even call it a strategy, won't work. Let's face the reality that the mentioned way of OP is something that anyone should not do even if they are whales or have a large bankroll. Any luck-based game doesn't have a mathematical way of sustaining the win in the long-run. That's not a recommended way.
Simply, if we bet a high amount then luckily we hit that, be satisfied with that win, and called it a day.
