Opensea Review: What could be improved?

Although the platform is a pioneer in this space, it still lacks in some departments and needs an immediate address for a better user experience.

Plagiarized content

One of the significant challenges plaguing the OpenSea NFT marketplace is the prevalence of stolen content and spam. In January 2022, OpenSea acknowledged that 80% of items created using its free minting tool were plagiarized, fake collections, or spam.

As a response, OpenSea briefly imposed limitations on the free minting tool but later reversed this decision due to user backlash. OpenSea does have mechanisms in place to address the issue. Users can report stolen content, and the platform strives to remove such content promptly.

Consequently, buyers must exercise caution and be more discerning when purchasing on OpenSea compared to platforms.

Frequent scams

As the largest NFT platform, OpenSea has become a prime scam target. Numerous attacks have occurred, one notable instance being a phishing attack in February 2022, resulting in the theft of hundreds of NFTs.

However, any NFTs you purchase or create on OpenSea are stored in your cryptocurrency wallet, minimizing the risk of direct theft from the OpenSea platform itself. Nevertheless, it remains crucial to remain vigilant against phishing scams, as they are prevalent within the NFT community.

Trustworthiness concerns due to insider trading

OpenSea faced a significant scandal in September 2021 when users discovered an inside employee frequently purchased NFTs before they appeared on the front page.

Henceforth, the crypto wallet associated with the individual sold those pieces after their prices had increased. This behavior resembled a form of insider trading with NFTs. While OpenSea has taken steps to address the issue, this incident has left a blemish on its reputation that may take time to rectify.
