In case the chain split has become reality, or even before that since there still is a 14 day of "waiting period", you'll already be too late to optimally profit from a hard fork. Bitcoin will suffer from a massive short term price decrease, possibly resulting in prices far below the $500 level. Things aren't as easy as you seem to think. In order to be infront of whatever is going to happen, you need to act in advance, otherwise you'll get eaten by the whales that don't show a signle grain of mercy to people.
