YouHodler, a fintech platform that helps both beginners and experts access the benefits of the crypto economy, has announced the winners of its campaign dedicated to highlighting the importance of cutting the carbon footprint of Bitcoin.

The winners of the YouHodler initiative to make Bitcoin greener are:

• Michael from Moscow, Russia, who won a Tesla Model 3

• Atlanta from Melbourne, Australia, who received a Vespa Elettrica scooter

• Jean-Pierre from Brussels, Belgium, who got an Electric Mountain Bike

Their photos can be found here.

The campaign was held from September 1 till October 31. All the prizes directly contribute to the reduction of the carbon footprint since switching to electric vehicles is considered one of the most important pillars for slowing climate change. YouHodler has also partnered with ImpactScope, which will offset the carbon footprint of the Bitcoin transactions made by the participants and donate to one of the following projects: grassland restoration in Kenya, wetland conservation in Borneo, or rainforest conservation in Brazil. Thanks to the collaboration, each participant could offset nearly 2.6 tonnes of carbon footprint (the total amount of emissions offset is 334.5 tonnes). 

“On the one hand, crypto tokens have their undeniable benefits that are shared by users all over the world. On the other hand, Bitcoin mining produces as much carbon dioxide as the whole country of Sri Lanka does in a year”, says Ilya Volkov, CEO & Founder of YouHodler. “As a responsible crypto company, we felt it was important to step in and push the industry to work on this issue and ultimately make Bitcoin green”.

YouHodler's solutions open up connections between crypto and the real world, allowing people to use their crypto assets without spending them. YouHodler helps people to learn the benefits of holding cryptocurrencies, avoiding negative or zero rates in comparison with traditional banks saving accounts. The key goal of the company is to make people stop passive holding and start using crypto assets right now. With YouHodler, users can buy and sell crypto at any time, use it for purchases or put it in a reward account generating up to 12% yields. In addition, they can exchange crypto, fiat, and stablecoins and get instant cash and crypto loans with their crypto assets acting as collateral.

vEmpire DDAO (https://v-empire.digital/), a project dedicated to restoring fairness to the Metaverse, today announced the launch of vEmpire: “The Beginning,” a blockchain-based two-player trading card game, that revolves around the expansion of a fictional empire by invading “decentraland,” a part of the metaverse and a tug-of-war for power between Romulus and Remus, two sons of a former emperor, staunch enemies of each other.

Romulus is a strong leader, who wins hearts with responsibility and promises of power and wealth. In contrast, Remus is sly and conniving, using underhand tactics to gain an advantage in a battle. While not as popular as Romulus, Remus cannot be bested easily in the long run.

Players get to choose which faction that they would like to play as. They will then be automatically matched up with an opponent taking the opposite side. Each faction has up to 40 faction-specific cards, as well as 12 universal cards that belong to both factions. When preparing for battle, players must choose 25 cards from their deck, which will make up their “Legion”.

“Each brother has at his disposal an army, with troops who have unique abilities. Players can choose their soldiers for different scenarios to counter any advantage their opponent might have. Players can either take an “all-out” attack approach, and throw their strongest troops at their opponent to win through brute force, or use tactics to outplay opponents by strategically removing their key players and increasing the number of cards in hand,” Dom Ryder, Founder of vEmpire said.

“Players are required to choose a faction and back a brother to the end, seeing him to his rightful place as the new Emperor. Players have to invest their time and resources to train their army into an unstoppable force, to conquer the Metaverse.”

Each player is randomly assigned a hand of 15 cards from their Legion. The remaining cards go into their “Battle Deck”. Although players' hands are dealt only 15 cards, some cards have abilities that enable players to dip into their Battle Deck, and access cards that they may not have been assigned in their original hand.

A virtual coin is flipped at the start of the game and the winner of the coin toss gets to play the first card. Players then take turns to play their cards until either both players decide to end the round or run out of cards.

Although the objective is to win rounds, there are a total of three rounds to play. This means that players will need to keep cards in reserve for later rounds. If a player runs out of cards before the game finishes, they will forfeit the following rounds. At the end of each round, all cards on the battlefield are sent to each player's respective discard pile and the following rounds are played with the cards remaining in the player's hand.

For holders of any of the Founding Soldiers NFTs, when choosing their Legion, if a card is picked for which they own the NFT for, they will be able to take the NFT and visually replace the generic card in play. While owning the NFT of a respective card will provide in-game boosts, the significance of the boost will not be overpowered and strategy will still primarily dictate the winner. In-game boosts simply give players an edge in battle.

Players are encouraged to have a powerful computer and graphics card to enjoy the games' fullest potential. The game is not currently operational on Macbooks. For more information and to download the game, visit: https://www.sandbox.game/en/create/game-maker/.

vEmpire (https://www.v-empire.digital/), a project dedicated to restoring fairness to the Metaverse, has partnered with The Antara Universe to develop the official Antara strategy game based on the upcoming $50M “Antara” feature film, the first Hollywood Movie in history supported by NFTs. The Antara film is part of a broader transmedia rollout by the Arabian Camels community, and also includes the “Antara Strategy Game,” developed by vEmpire. Both Antara IP and vEmpire understand the importance of building utility for NFT projects, so holders of the Arabian Camels and The Founding Soldiers, vEmpire's NFT series, will automatically qualify to be gifted tokens for the official Antara game via an airdrop. 

The Antara film will be supported by the sale of new upcoming Movie NFTs, which will be a sequel to the original Arabian Camels NFT collection of 12,012 uniquely generated digital collectibles living on the Ethereum blockchain.  

The first iteration of Arabian Camels (Gen 1) available on OpenSea, provides added boosts and benefits for gameplay such as the ability to use Camels to conduct raids in the game. Players who don't own Camels can also effectively rent them from the NFT holders to enable more advanced & potentially higher-yielding gameplay. The upcoming Gen 2 Arabian Camels Movie NFTs will include exclusive rights to the Antara movie, allowing for shared ownership of the IP. Demand for the NFTs is expected to increase exponentially given the launch of the game and movie in the coming months. 

“vEmpire DDAO was an easy choice to partner with for our game production. vEmpire has the unique ability and experience in not just one, but across all of the major Metaverses. Alongside this, their own gaming experience and multidimensional thinking gives us a broader scope when choosing where Antara can put its roots down,” said Alexander Amartei, producer of Antara.

“It's a great honor to partner and be involved in a project that will go down in history as the first of its kind. At vEmpire, we understand that NFTs are a disruptive technology that will significantly improve a multitude of industries. Developing the official game for a historic feature film, that will change the landscape of how movies are produced, is something that we're very excited and proud to be involved with,” commented vEmpire founder Dom Ryder.

This is a monumental achievement for vEmpire as it signifies another major partnership, this time partnering with a historic project, to develop the first blockchain-based game based on the first feature film supported by NFTs. This will help vEmpire expand its reach in the metaverse and benefit from any tokens launched for the game and in-game revenue generation.

The Arabian Camels NFTs are available on OpenSea and the new upcoming Movie NFTs, soon to be released, will enable NFT holders to own partial movie rights to the film. 

More information surrounding the upcoming Antara film can be found on the official website or by joining the Arabian Camels Discord community.
