Introducing a groundbreaking token designed to bestow substantial rewards upon its top and fortunate holders.
The concept is elegantly straightforward: when the token's market capitalization reaches the 100 million mark, 
we will initiate a liquidity withdrawal event, channeling the entire liquidity pool to the top 10 token holders 
and extending the opportunity for equivalent benefits to 5 lucky holders. The distribution plan unfolds as follows:

85%: Allocated to the top 10 holders in a proportional manner, rewarding those with larger stakes commensurately.
This approach fosters an environment where committed investors reap the lion's share of the liquidity pool.

15%: A novel aspect of our model, 5 lucky holders, chosen through a predefined and transparent mechanism, 
stand to share an equitable portion of the liquidity. 
This element adds an element of excitement and surprise for participants.

This innovative system not only incentivizes major investors or "whales" to drive the token's market price towards 
the 100 million threshold but also holds the potential to provide significant windfalls to those fortunate enough 
to be deemed "lucky" during the distribution event.

Security Warning: It's important to note that while this distribution model offers the potential for substantial rewards, 
there are inherent risks involved. When the market capitalization reaches 100 million, the liquidity withdrawal may lead 
to significant price volatility, and there's a possibility that some investors may incur losses or lose their entire investment. 
As with any investment, please exercise caution and consider your risk tolerance before participating in this project.

LP withdrawal condition:
1. Completely pulled out and distributed to top holders and lucky holders once Marketcap reaches 100M
2. Within 1 month by owner if marketcap does not reach 100M(lock can be extended)

Ownership will be renounced but there is a specific governer role which can withdraw the liquidity after specific time.
