Hi although others have answered your question let us also explain a little.
Firstly, we are NOT a lending platform, far from it. The only resemblance we have is that you can use a referral link to make money, that is as close as we get. The way it works is you put in ETH into the contract and 10% is taken upon entry and 10% upon exit, and both of these 10 percents are shared amongst other holders, so whenever anyone leaves or joins the contract, as long as you have LCK tokens then you will receive dividends which you can either reinvest or withdraw as ETH without penalty (the 10% for exiting does not apply to Dividends).
The contract cannot be adjusted/changed/altered or tampered with in any way by any humans so it is set in stone. You are basically investing in a dividend paying smart contract that is not able to be scammed or hacked or owned by any-one person, the whole funds are within the contract on the Ethereum Block-chain and unless ETH disappears the contract will run for eternity.
The 33% you are referring to is paid to you, or anyone who shares their master-node link and someone else joins up with it, so you get a referral bonus from that community 10% and everyone else also gets paid. The contract will auto-generate a master-node link for you if you hold 30 or more LCK tokens.
Anytime someone leaves or enters the contract you are paid!
As others have mentioned we have one Beta game currently near completion which means you can bet on heads or tails and one will win one will lose but the great thing is that everyone who is a holder of LCK will receive dividends from this, every single time anyone bets or plays.
So we have the most unique Smart contract passive earning program which will soon include lotto and futures betting markets and every-time someone bets or plays, regardless if you do or not, you will receive a dividend from that evolution.
Our volume is low at the moment, but those who are already in, or about to get in, the smart ones that is, will reap the rewards once we have all of these extra functionalities live in the near future so if anyone is considering getting into LOCKEDiN, now is the time to do so, before the price is high.
Remember, the Smart Contract is "LOCKEDiN" but your funds are not, you can withdraw and exit at ANY time you choose.
Hope that explains it a little clearer for you and thank you for your question.
