POWH 3D Can the contract be changed or removed by the authors?

Thanks, tljenson for your questions. Here are your answers:

1. Not unless it is coded to allow itself to be destroyed. The PoWH3D contract does not have any such code in it.
See http://solidity.readthedocs.io/en/v0.4.21/introduction-to-smart-contracts.html#self-destruct
Please also see the PoWH3D code review: https://youtu.be/gDpOTL_KKys

2. See answer one

3. See answer one

It is important to understand a project before investing in it. The smart contract of PoWH3D is open and transparent and a lot of people assuming things and scenarios that are impossible to happen. They just have to look at the code and understand the uniqueness and revolution in the PoWH3D smart contract and beyond the project itself.

I hope you don't mind, that I use your thread to catch up with info about PoWH3D and raise new awareness about this revolution in the crypto space. So let's get started...

PoWH3D summary:
PoWH3D is a decentralized economic simulation of an algorithmically governed cryptocurrency in which the taxes on all transactions are awarded autonomously to currency owners instead of a governing body; resulting in a universal passive income based on adoption and transaction volume.

PoWH3D is a unique cryptocurrency exchange which allows you to trade Ethereum for P3D tokens. P3D tokens are ERC-20 tokens with a clever twist: Every P3D holder receives direct earnings in Ethereum every time that anyone else buys, sells or trades the token based on the amounts of tokens (in % out of total amount minted) held.

What's coming next:
The PoWH3D development team has a long-term vision that spans much farther than any one project. There are at least 4 upcoming projects planned and each is distinct and complementary to one another. These projects form a brand new ecosystem. The best part is that each of the projects in the ecosystem will reward strong holders and users of the others. There is no need to sell P3D tokens ahead of the launch of future releases. Instead, having strong hands will only benefit you as the ecosystem develops. The developers don‘t ask for nor want your faith or belief, only that you have fun, think critically and keep an open mind.

FOMO3D, the next smart contract will go live in May 2018. P3D holders will gain serious benefit from owning tokens.

I'm not a financial advisor, but I recommend looking closely at PoWH3D. If you are comfortable with the project, then buy into P3D, hold your tokens long term, enjoy the dividends and thank me later.
