Total Supply: A total of 1,000,000,000,000 tokens are available at launch.
Buy Fee: On purchase there is a 10% total tax (6% goes to the holders, 4% to the team for marketing).
Bot Protection: The first buy of SAZANKA is capped at 3,000,000,000 tokens, 45-second buy cooldown for the first 2 minutes after launch.
There is also a 15-second cooldown to sell after a buy to ban front-runner bots. There are no cool downs between sells.
The sell fee is dynamically scaled to the sell's price impact, with a minimum fee of 10% and a maximum fee of 40%.

Stealth Launch Soon!💨💨💨
Tornado Inu is a brand new idea of community reward base inu token. Tornado inu a lethal combination of wind and power inu. Our aim is to destroy all other meme tokens. 💨
Tornado is community reward based. We require all token holders to shill tornado inu to other meme token telegram groups. Most of the tax will be shared by the token holders who shill over 10 messages to other groups.
Tornado is also a deflationary token. 3% of each transaction will go to auto-burn. So, all the holders could enjoy the valuation increment by just hodling.

* @dev Wrappers over Solidity's arithmetic operations with added overflow

* error, which is the standard behavior in high level programming languages.
* `SafeMath` restores this intuition by reverting the transaction when an
* operation overflows.
*
* Using this library instead of the unchecked operations eliminates an entire

HADOKEN INU 🔥FAIR LAUNCH SOON 🔥
Hadoken Inu is where legends are reborn and recreated within the realm of powerful decentralization and community starting with the Ethereum blockchain.
Hadoken Inu will bring Anime and Arcade together in the most exciting way yet seen via a community run ecosystem of mini P2E games.
Our first legendary game on the horizon is "Roji Fighter" which is our very own streetfighter inspired game (Preview coming soon)
🚀 Launch Details 🚀
🗓 Date: TBA (SOON)
🔒 Liquidity Locked- Shortly After Launch
💎 Token Details 💎
🚀 Name: $HADOKEN
👀 CG & CMC Fast Tracked!
⛓ Blockchain: Ethereum ERC-20
⚖️ Total Supply: 1 Trillion
🦾 0% Tax = NO TAX!
🦾 Full supply going to Liquidity = No Team tokens! & No Presales!
🦾 Team funded liquidity = commitment + No dump from pre-salers!
👮♀️ Anti-sniping measures in place!
🔥 Temporary buy limit for fair distribution on launch!: TBA

We have a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells, as a result; $SHIBONE is designed to reward holders and discourage dumping.
1. Bot and whale manipulation prevention: Buy limit and cooldown timer on buys to make sure no automated bots have a chance to snipe big portions of the pool.
2. No Team & Marketing wallet. 100% of the tokens will go directly to Uniswap for trading.
3. No presale or team wallets allocated with tokens that can dump on the community.
Token Information:
1. 1,000,000,000,000 Total Supply, but we're burning 10% of this imemdiately to create a super deflationary mechanism within the tokenomics!
3. Developer provides LP and it's locked with Team.Finance
4. We have made the fairest possible launch for everyone and pre-announced, so there is no early secret buyers!
5. 0,5% transaction limit on launch - You can only buy 5000000000 $SHIBONE until it's lifted
6. Buy limit lifted to 1% of the supply 5 minutes after launch, then the ownership of the token is immediately renounced
7. Sells limited to 3% of the Liquidity Pool, <3% price impact - Anti dump mechanism
8. Sell cooldown increases on consecutive sells, 3 sells within a 4 hour period are allowed
9. 2% redistribution to holders on all buys
10. 6% redistribution to holders on the first sell, increases 2x, 3x on consecutive sells
11. This redistribution mechanism works as expected above and benefits the holders much more than sellers!
