Bitcoin betting attracts me, for example one of the main reason is what you already said. But that can't be considered as a gambling strategy. I know you mean that way if you win, then you won't gamble and prefer to exchange coins but not a big deal. If price falls, depends on fall, you may gamble just to get your first money back but if you are a person who holds, then won't do. Well if you are gambler, that doesn't matters, really. Even it can be a sad fact when you see you have lost coins which were 100$ but now are 5K worth.
