What is POM Inu?

Branching off Proof of Memes and Pomeranian, POM Inu strives to become the top community-driven meme token.
We are developing a currency for the people and by the people, utilizing blockchain technology for security.

Tokenomics:

Total supply: 1 Billion
Max tx: 2%
Buy tax: 2% auto LP & 3% marketing and buyback = 5% total 
Sell tax: 2% auto LP & 3% marketing and buyback = 5% total 

NOTE: There will be a 15% sell tax applied for the first 24 hours of any purchase. After 24 hours have passed from the purchase time,
the sell tax will be 5% again. This is to encourage holders to hodl as well as to build a stronger LP early on and decrease the supply
at a higher rate when people sell early. Overall, this benefits all long-term holders by increasing the price faster with each auto LP add,
and making sells have less of an effect on the chart.
