No since there is now way anyone can run away with the money at the end unfairly. This is all thanks to it running as a smart contract so all payments are done autonomously, no humans required.
It is however gambling since you are estimating that the pot will still grow much bigger than it is now. If you think it will keep going longer, then buy as many keys as you can to earn as much dividends as possible. Remember that dividends can be redeemed anytime once given to you.
