when you have no strategy or negative EV the best bet is to be a maniac. bet it all. this is true in everything.
Of course you only live once. Why not give it all???!! Even if you didn't get rich, you still end up a legend, like Jesse Livermore. Napoleon said it the best: "There is no immortality but the memory that is left in the minds of men...to have lived without glory, without leaving a trace of one's existence, is not to have lived at all.”
