$SAITAMEOW
Launching tomorrow. Haven’t worked with the team before but i think it’s a safe dev.
Saitameow is a community based meme token that plans to take off with the help of influencers and upcoming utilities/merchandise.
🚀 Anime + Cat Meta ERC-20 Memecoin
🚀 P2E Meowverse planned for v2 Roadmap
🔥 50% of supply burned at launch + 1% AUTO-BURN
🔥 Max TX & Anti-bot measures for smooth/fair launch
🔥 Automatic Reflections + Burn + Liquidity = BULLISH

Have you imagined your illustration can be the next viral NFT artwork but you have no idea how to start? Inustrator is here for you!
Inustrator is designed as an enabler, assisting talented artists to express their potentiel artwork.
We sincerely invite talented artists to submit and share your work and we will help you to publish it as an NFT with our Inustrator Fund.
The purpose of Inustrator Fund is to initiate fund for artists to promote their artwork. The source of our fund will be extracted from every transaction you made on our token.
In order to find out which artist is the best of the best. Our goal is to create a “simple voting portal” Inustrator DAO will poll vote among Inustrator owners.
The voting result will instruct Inustrator to invest in which artist and turn it as the next viral NFT,
ALL of the tax fee from Inustrator will be distributed to invest in the artist.
Inustrator DAO aims to be a world-class Crypto Project Investment Fund along with the increase of Inustrator DAO users.

SEIZE the memes of production !!!!!
Have you ever wondered why a meme could become so powerful?
Do you think memes are all about a normal picture filled with funny content OR you already know memes could be a powerful cultural weapon that can have a significant impact on our daily lives?
Memes are carriers of cultural information.
The images at the beginning of this post are clear examples of memes in this sense, not because they made you laugh
(or, more than likely, cringe), but because they allowed for the transmission of culturally salient information.
One meme could become viral simply because it contains vast popular information.
We believe that the cryptoworld is the best place to indicate and show how powerful one meme is.
Shiba is one of the best and significant examples to show how powerful one meme can be,
various projects are named after Shiba and most of them turn out successful.
Combining the power of Shiba and the meme, we deliver MemeShiba to maximize the memes of production! Join us and SEIZE the memes of production !
