NFTs have become one of the hottest crypto trends of 2021, with large companies like Facebook, Visa and Alibaba jumping in on the NFT bandwagon.
In the second quarter of 2021, the sales volume of NFTs surged to new heights, hitting $2.5 billion in sales so far this year. This makes it clear that NFTs are here to stay.
Here are a list of marketplaces where you can buy, sell and trade NFTs:
1. OpenSea

OpenSea dubs themselves as “the world’s first & largest NFT marketplace”. They are regarded as behemoths in the NFT marketplace space, with overall transaction volume surpassing over $3.4 billion in August, 10 times of that the month before.
OpenSea houses anything from music and art to virtual reality, trading cards and sports NFTs. Even items from popular NFT games like Axie Infinity, CryptoKitties and Decentraland can all be found here.
The platform recently raised $100 million with a $1.5 billion valuation in July, which is one of the highest valuation figures for a NFT marketplace. This further establishes them as the leader in enabling access of NFTs to the general public.

2. Rarible

Rarible is a community-owned marketplace, with its owners holding the Ethereum-based RARI token. The platform focuses mainly on digital art,
As an incentive to build an active community, users on the platform who buy or sell NFTs on the Rarible marketplace are rewarded with 75,000 worth of RARI every week. Rarible is the best-in-class platform to earn royalties on selling NFTs, with rates reaching up to even 30% as compared to OpenSea’s 10%.

3. SuperRare

SuperRare is a marketplace to trade and collect one-of-a-kind, single-edition digital artwork. Each artwork is created authentically by an artist on the network, and tokenized as an NFT that you can own and trade.
SuperRare claims themselves to be a mix of Instagram and a stock exchange/auction house, and instead of community votes to verify each artwork’s listing, the SuperRare team verifies artwork themselves to ensure the platform is equipped with only quality NFTs.
As they’re in early access mode, SuperRare only works with a handful of leading concepts artists to create digital art, and artists have to submit their profiles through an online form to list their NFTs.

5. Nifty Gateway

Nifty Gateway is an online NFT auction house owned by cryptocurrency exchange Gemini. Nifty Gateway differs from other NFT marketplaces in that users are able to pay with their credit cards, and they don’t require a Metamask or any digital wallet.
Nifty Gateway combines centralised processes with a decentralised system for a more user-friendly experience. However, this might be a deterrence to die-hard decentralised users.
Digital artist Mike Winkelmann, known as Beeple, made record news in March when his NFT titled “Everydays: The First 5000 Days” sold for over $69 million on the marketplace.

6. Foundation

Foundation is a P2P online marketplace where artists sell their digital art, and are also able to invite other artists to join the platform through their own single-use invite code.
Before an artist can build a profile, they have to either mint their own NFTs or purchase artwork from the site. Profiles are then verified through community upvotes. This ensures the hands behind the artwork are invested in their thriving community.
