Is OpenSea a good investment?

Currently, OpenSea is the first and the largest NFT marketplace in the crypto world. Therefore, with a strong community, it’s hard for other similar projects to compete with OpenSea. There are some key highlights from Coin98 for investment decisions.

Technically, the OpenSea platform was initially built on Ethereum in 2017. However, in 2021, the Ethereum blockchain raised lots of problems such as the gas fee and the transaction speed. Therefore, Polygon and Klaytn were integrated into the platform as alternatives to Ethereum. They all work in parallel and users can choose regarding their needs. 

Since Jun 2021, we have witnessed the rapid growth of OpenSea with hundreds of million dollars daily trading volume and almost 50,000 DAU (Daily Active Users). The following chart shows the growing momentum of OpenSea.

OpenSea is the second Dapp having the highest revenue in the crypto world with total revenue of over $200M, behind the NFT game Axie Infinity. This means the OpenSea platform is a profitable business model and they can maintain and develop the platform with the revenue generated. This derives mostly from the 5% fee of the total NFT price.

OpenSea Revenue since launch

OpenSea hasn’t released its tokens yet. Therefore, the possibility of token airdrop as a retroactive program is high. There were other retroactive airdrops from successful platforms such as UniSwap or dYdX to their early users. This might be a similar case with OpenSea since the platform has raised many funding rounds and achieved certain successes.

And as usual, whether it is worth investing or not, Do Your Own Research before buying and be responsible for your investment.
