Would wait. The game is stacked against further rise. It appears overheated due to the two successive launchpools (BNB always jumps up when launchpools / -pads are announced). Furthermore, orderbooks point at an impeding correction. My guess is that in 6 days, when the current launchpool closes, BNB will retrieve back to below 290. Doubt it will be go all the way to 250 though.
