On top of that, the devs managed to pull some of the funds before it was all taken away, which means they have the ability to withdraw funds from the contract, so after the ICO they could just pull everything out and run away with the money, and since they decided to be anonymous, no one can track them down.

Scammers everywhere! I am almost certain my investment in Plexcoin is lost and gone. A huge price for inexperience on my part.

Men.!! What will happened next? I also feel really bad about it..!!

SmartBillions Official HACKATHON Announcement

We would like to congratulate the first person to withdraw the funds during the  hackathon and emphasize our happiness with the outcome. This is a great possibility to implement any final smart contract security solutions to guarantee comprehensive Investor and lottery protection. Congratulations to https://etherscan.io/address/0x6245c1804f7fceb305a60bbb5cb6e18f939edb69.

The SmartBillions hackathon was held as a final validation of the smart contract security and to secure future ICO Investors funds. The most important goal of the hackathon has always been and will be Investor funds protection. We witnessed the best possible scenario as the leak was indicated during the hackathon process and not after the start of the ICO. We strongly believe in this community audit mechanism and therefore the next hackathon will begin today, based on the revised smart contract.

As we learned, the function “putHashes”  was not executed by the admin as required. The hackathon allowed the team to improve the smart contract in order to validate it finally. The administrative strategy has been changed now to protect the investors the security of the contract will not require a continuous acitivity of the Admin. The updated smart contract is now available online at https://github.com/SmartBillions/SmartBillions/blob/master/SmartBillions.sol. The new Hackathon will now commence with the same prize of 1500 ETH. Later today a detailed description of the improvement will be published together with the description of solutions and modifications made within the smart contract. SmartBillions Team will be happy to answer all possible questions concerning the course of the hackathon.

The execution of the hackathon allowed community members to find the leak in the smart contract and later implement further security solutions to conduct one more hackathon validation.
The funds were withdrawn by Admin, only because there was no smart contract commitments, such as wins payouts or Token redeeming. If interested, please see the SmartBillions smart contract to see limited funds withdrawal possibilities.

But what's worrying is that you were able to withdraw the funds, it should not have been possible especially After talking so much about the independant contract no one can tamper... What proves now that you won't be able to withdraw funds once you'll have funds from the ICO?

But what's the guarantee you won't be able to withdraw funds from the real contract ?

I will wait to see if someone can analyse the code to see if there is no backdoor

very interesting to look forward and continuation of this project. one question, is ICO will delay? or on schedule? 

I think it will still be on schedule. And I still believe this project will goes on, another improvement will come then no one can break again into it. Everyone learns from mistakes, security will goes wilder than before, so better to watch this project because this is were things goes interesting.
