For some, a casino in a pocket is a cryptocurrency exchange. It's probably even worse to trade with leverage than to click this colorful buttons.

At least children can't sign up for a Robinhood account.

At least on the stock market, assuming the Efficient Market Hypothesis, the expected payout is 100% minus fees.

For others it's the Robinhood app

On a trading exchange at least you have the theoretical possibility of winning more than you put in.

How come such an article ends up with 30+ points? There's literally no meaningful information. I'd look into what accounts upvoted this link, something seems off.

There are supposedly many introverts frequenting HN and longing for any help they could get in building their network. Some of them probably reflexively upvoted the article without looking at it first. Since it's impossible to un-vote a story, those upvotes remained even as they came back here to complain about lack of meaningful content in the article.

> Since it's impossible to un-vote a story

When I vote a story, an "unvote" button appears to the left of the "parent | context | flag" buttons. Are you saying that it doesn't work?

No... I just honestly didn't notice it's there! Will need to check if it works next time, thanks for the tip :)

The article is shit; I just wanted to encourage more discussion on the topic in the comments.

Many of us upvote seemingly useful titles before reading the article. This one turned out to be clickbait.

Honestly I read this website for the comments 70% of the time.

Flag bad articles and email the mods if you suspect abuse otherwise the forum fills up with meta.

72 now..

lesson learnt.. clickbait titles is a real thing

tl;dr; Tacit knowledge is knowledge that cannot be captured through words alone. Think riding a bicycle.
