I noticed this too.. but its back down again, probably someone wanted to buy into POB with a big stake that temporarily pushed the price up.

as for staking, the rewards have a really high yield, at the moment as the coin is in its infancy, so staking is a really good option if you want to curate and contribute to the community, but if that's not your thing and you want to trade the coin that's beneficial to the community too, as it provides liquidity in the markets.
