On the importance of leverage for the crypto ecosystem.
A long time ago, BNP Paribas bought a retail forex exchange, because they thought they'd get an insight into forex trading flows and positions. What they quickly discovered, is that the website was a muppet slaughterhouse.

People would get stopped out ALL THE TIME because they used too much leverage. Over 90% of them lost money in a consistent way. Those are worse than even casino odds.
That's why around 2005, you had so many forex trading websites popping up. They would offer up to 500x leverage.

The higher the leverage, the better (for the website).
This became such a huge trend that regulators stepped in, and introduced maximum leverage rules. Something like x30 for forex, if I remember correctly. All of a sudden, all the ads and Premier League sponsorships vanished.

Forex gambling is still around, but not nearly as profitable, because it takes time for people to lose their money with a pitiful x30 leverage. Currencies usually don't move by 3% in a day. It can take weeks for an amateur trader to lose it all. Plus the adrenaline rush is gone.

Enter crypto.
It's hard to explain how one-sided leveraged crypto trading is. Traders don't stand a chance. With currencies, you could expect to extract SOME money from real world flows. In crypto, there are no real world flows. It's just traders against traders against insiders.
