🔸♦️🔷Brick INU🔷♦️🔸

ONLY THE BEST IS GOOD ENOUGH. LET'S BUILD THE BEST COMMUNITY OF ALL, BRICK BY BRICK.

⏰⏰Lanuch time: Saturday 24/07/2021 @ 20:00 GMT

💁🏻‍♂BRICK INU is an ETH reflective, NFT enriched and Lottery oriented ERC20 community-driven meme token with the vision of maximizing profit for BRICK holders employing many of its unique features.

🧮 BRICKoNOMICS:
2,500,000,000,000 Total BRICKs 
7,500,000,000 initial buy limit 
30 Sec Cooldown

💠 BRICKoTRUST:
Liquidity Locked on Unicrypt
Ownership WILL NOT be renounced, we need control over the contract to take action. In fact, this is the most stupid thing to do!!

💲 BRICKoFEES:
12% Tax as following:
       >  7% for Distributin in ETH among 3 BRICK Holders every 30 minutes  
       >  4% for Development & Marketing
       >  1% for Buyback & Burn

🎟 BRICKoLOTTO:
This is the most exciting part of our ecosystem. We have designed a lottery system to incentivize community to hold and flaunt their holdings. 60% of all collected fees will be distributed to 3 lucky winners on every lottery draw. BRICKoLOTTO has the following criteria:
        1) Instead of giving equal weights to all users, we give weights based on their purchase token amount and contributed ETH amount
        2) The amount of BRICK should have been bought by the same address and not transferred to another address. If you do so, you'll lose your chance to be included in the ETH reflection, unless you buy again with that wallet. You got no place in BRICKoLOTTO you filthy multiple-address-smart-contract buyer.
        3) There's no min eligible amount. Even if you buy 1 token, you have the very little chance to get rewarded.
        4) Every 30 minutes, 3 wallets will be randomly chosen for ETH reflection on their wallets. No action is needed and ETH will be reflected to your wallets seemlessly. However, the time between lottery wllaets selection can/will be changed after launch according to community votes.
        5) We will announce the 3 winners every time it changes on telegram channel. 

🖼 BRICKoNFT:
This is the next area in which BRICK shines. With BRICKoNFT, you can mint your own LEGO-themed NFT, every of which are unique and not mintable by anyone once deployed by BRICK stakers. All minted BRICKoNFTs will be tradable right away in NFT marketplaces such as OpenSea and Rarible. This has never done before and will be a game changer once live.
In order to be able to mint a BRICKoNFT, you should stake and burn a certain amount of BRICKs which will be decided before it is fully launched. Keep in mind that the burning requirement make BRICKs even more deflationary and valuable.
