* Coming to www.lockedin.io this weekend.
*
* An autonomousfully automated passive income tokens:
* [x] Created by a team of professional Developers from India who run a software company and specialize in Internet and Cryptographic Security
* [x] Pen-tested multiple times with zero vulnerabilities!
* [X] Able to operate even if our website www.lockedin.io is down via Metamask and Etherscan
* [x] As people join your make money as people leave you make money 24/7 – Not a lending platform but a human-less passive income machine on the Ethereum Blockchain
* [x] Once deployed neither we nor any other human can alter, change or stop the contract it will run for as long as Ethereum is running!
* [x] Unlike similar projects the developers are only allowing 0.3 ETH to be purchased by Developers at deployment - Fair for the Public!
* - 25% Reward of dividends if someone signs up using your Masternode link
* - You earn by others depositing or withdrawing ETH and this passive ETH earnings can either be reinvested or you can withdraw it at any time without penalty.
* Upon entry into the contract it will automatically deduct your 10% entry and exit fees so the longer you remain and the higher the volume the more you earn and the more that people join or leave you also earn more.
* You are able to withdraw your entire balance at any time you so choose.
