Beauty premium is a concept that's mostly related to the preference or bias that's given to individuals with a good look over their counterparts. It's the reason why good-looking individuals experience higher chances of getting a job over their less attractive counterparts. It's not just applicable to the job sector but also applies to the crypto space.
This is true and it's mostly found in female genders. And it is something that is bad this is because most of the people employed because of their beauty cannot easily execute tasks or do the jobs properly. This may cause the downfall of the company or organization. I think it is foolish to pick someone because of their beauty if it is not a requirement. I know of some jobs like a waitress in the hotel, they mostly pick the beautiful ones so they may entice men to stick around the hotel often. It's part of business strategies. But if the work doesn't require such then beauty shouldn't be a criterion.
Some crypto enjoys beauty premium based on market sentiment rather than it intrinsic value. For instance, a crypto with strong community, large number of followers, good marketing strategy, high visibility and that's well branded with appealing user interface can easily attract investors and influence investment decision even when it's a possible scam project.
Like you, it's also applicable in the online space. Crypto or noncrypto. Several websites or platforms online are now using beautiful interfaces to attract users. Especially some social media apps which I do not want to mention. Some users would always think they are real not knowing they are purely scams. It is mostly found in dating apps and some crypto apps. Most times it is the platform with the funky look that seems to offer the right services.
