UN-PEGGED STABLE

Stables are losing their peg to the dollar at the moment. USDC is the preferred stable coin. 

This bear market has affected many of us in the Crypto Space and we have decided to help those that lost alot during these times by rewarding them in USDC Rewards. Every holder will constantly get USDC as long as they HOLD and Un-pegged Stable $USP.

Moon Mission: Getting to $1

We aim at reaching a value of $1 per $USP. Starting with a low market cap and total supply of 1 million $USP, this will be possible by a community of diamond hands. The team is ready to deliver in all aspects.

TOKENOMICS 

8% BUY & SELL
 ├ USDC Rewards 3%
 ├ Marketing 3%
 └ LP 2%

Team
Our vision as a team is to bring value and adoption of cryptocurrency to the world, build a strong project and
 community. We are set for moon landing with professional marketers equipped with a shill army as well and 
 dedicated dev team. With our team and use case, there will be no stopping
us.

ROADMAP


PHASE 1
