Elon is one of the hero leading the cryptocurrency that brings us gigantic buy momentum!
We all love to see a gigantic lovely green candle in the chart field, but have you ever wondered why green signifies a positive meaning in the graph? The green candle elon is about to reveal the secret behind it for you!
Green Is Calming
Shades of green in nature can help put us at ease in a new place and hopefully can ease our tension when we face a new project!
Green Is Natural
Green's calming effects might result from its association with nature, which people typically experience as relaxing and refreshing. Some researchers think the positive association with green is hardwired in our brains from evolution. Early humans knew that green in nature indicated a place where they could find food, water, and shelter. Now we know Green doesn’t only signify where we could find food, water, and shelter but also potential and based project.
Green Is Motivating
Although some find green a relaxing color, others say it motivates them. Although some find green a relaxing color, others say it motivates them. I am sure everyone of us knows how motivated we could be if we could see an enormous green candle!
Now you know the secret behind green color and how it affects our psychological status! Join us and create a big green candle with The lovely green candle elon!

🔸♦️🔷LEGO INU🔷♦️🔸
ONLY THE BEST IS GOOD ENOUGH. LET'S BUILD THE BEST COMMUNITY OF ALL, BRICK BY BRICK.
⏰⏰Lanuch time: Thursday 15/07/2021 @ 20:00 GMT
💁🏻♂️LEGO INU is a reflective, NFT enriched and Lottery oriented ERC20 community-driven meme token with the vision of maximizing profit for LEGO holders employing many of its unique features.
🧮 LEGO.NOMICS:
2,500,000,000,000 Total LEGOs
7,500,000,000 initial buy limit
1 Min Cooldown
💠 LEGO.TRUST (https://legoinu.com/):
Liquidity Locked on Unicrypt
Ownership Renounced after everything works as intended
💲 LEGO.FEES:
5% LEGO Redistribution among Holders
15% Tax as following:
> 50% for Development
> 40% for Marketing and Buybacks
> 10% for LEGO.LOTTO to Reward Top Holders
🎟 LEGO.LOTTO (https://legoinu.com/):
This is the most exciting part of our ecosystem. LEGO architect has designed a lottery system to incentivize community to hold and flaunt their holdings. 10% of all collected fees will be distributed to 3 lucky winners on every lottery draw. LEGO.LOTTO (https://legoinu.com/) has the following criteria:
1) You need to be among top 20 holders until the deadline of that lottery draw.
2) The amount of LEGO with which you are a top 20 holder, should have been bought by the same address and not transferred from another address. You got no place in LEGO.LOTTO you filthy multiple-address-smart-contract buyer.
3) If you were chosen as one of lucky winners, you must maintain the same amount of LEGO holdings until the next lottery draw. Otherwise, your spot will be given to the next person who has held until the next lottery draw (even though he was not among the 3 winners).
4) The first lottery draw will happen at 5 hours post launch, following by daily lottery draw at the same time of the day.
5) At the end of each deadline, a random number will be assigned to each of top 20 holders and before the draw, a google sheet containing all eligible entries will be shared in our telegram channel.
6) The LEGO.POT for every draw is shown on the front page of the website live.
🖼 LEGO.NFT:
This is the next area in which LEGO shines. With LEGO.NFT, you can mint your own LEGO themed NFT, every of which are unique and not mintable by anyone once deployed by LEGO stakers. All minted LEGO.NFTs 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 LEGO.NFT, you should stake and burn a certain amount of LEGOs which will be decided before it is fully launched. Keep in mind that the burning requirement make LEGOs even more deflationary and valuable.

* @dev Implementation of the {IERC20} interface.

* For a generic mechanism see {ERC20PresetMinterPauser}.
*
* TIP: For a detailed writeup see our guide
* https://forum.zeppelin.solutions/t/how-to-implement-erc20-supply-mechanisms/226[How
* to implement supply mechanisms].
*
* We have followed general OpenZeppelin Contracts guidelines: functions revert
* instead returning `false` on failure. This behavior is nonetheless
* conventional and does not conflict with the expectations of ERC20
* applications.
*
* Additionally, an {Approval} event is emitted on calls to {transferFrom}.
* This allows applications to reconstruct the allowance for all accounts just
* by listening to said events. Other implementations of the EIP may not emit
* these events, as it isn't required by the specification.
*
* Finally, the non-standard {decreaseAllowance} and {increaseAllowance}
* functions have been added to mitigate the well-known issues around setting
* allowances. See {IERC20-approve}.

This is a new token that going to distribute BitCoin to all holders via reflections. It’s paid out automatically.
In my opinion, this token will be huge since it’s the first one that they started to distribute BTC (as far as I know)
Marketcap will be 30K$
$bSATOSHI
👩💻Website - https://babysatoshitoken.com/
💬Telegram - https://t.me/babysatoshiuni
💸 Tax: 14% Tokenomics (8% Redistributed among holders in BTC, 6% Marketing.) on sell.
🌐 Liquidity: 100% locked for 6 months

* `SafeMath` restores this intuition by reverting the transaction when an

*
* Using this library instead of the unchecked operations eliminates an entire
* class of bugs, so it's recommended to use it always.

FARM is the official token for Baker Farms. You will be able to purchase plots of land as well as animal crates using FARM.
Baker Farms is a multiplayer builder game, introducing blockchain to millions of players. Anyone can buy and own virtual islands, collect and build exciting items and meet new friends.
Inspired by successful games such as Animal Crossing, the game combines the best of the two worlds - a fun narrative for regular players who want to enjoy the gameplay experience as well as an ecosystem for players who want to collect and trade NFT:s, even if they have no idea what an NFT is.
This project is well funded and imposes 0% Tax for buyers. Tax will be charged only when using FARMS to purchase NFTs.
Liquidity will be locked for 5 years via Team by TrustSwap. Check out our telegram and website to learn more!
