We have a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells, as a result; $ePugdog 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:
- 1,000,000,000,000 Total Supply, 30% is burned immediately
- Liquidity provided by ePugdog devs and then locked with Unicrypt
- Using the fairest possible launch method for everyone and this is pre-announced, so there is no early secret buyers! 
- 0,2% transaction limit on launch - You can only buy 2,000,000,000 $ePugdog until it's lifted
- Buy limit lifted to 1% of the supply 30 minutes after launch, then the ownership of the token is immediately renounced
- Sells limited to 4% of the Liquidity Pool, <4% price impact - Keeps the whales out and prevents issues people have seen with SHIBCAKES & MYOBU
- Sell cooldown increases on consecutive sells, 5 sells within a 24 hours period are allowed
- 2% redistribution to holders on all buys
- 7% redistribution to holders on the first sell, increases 2x, 3x on consecutive sells
- This redistribution mechanism works as expected above and benefits the holders much more than sellers!
- 4% developer fee split within the team
- Smaller cooldown periods than Myobu, but still prevents frequent dumps and sell pressure
