Sketchy forex trading?

Those guys are usually always selling some system/signal service and forex is the best way to sell it. It's 1000x easier to appeal to the average Joe that doesn't have $25,000 or w/e. Forex is also pretty much marketable to anyone from anywhere. A shitty, unregulated OTC product so it can be traded wherever in the World as long as there is a broker. Plus some brokers actually give you 100-500x your account value despite your initial deposit being something as silly as $1,000 (these are usually bucket shops that aren't actually giving you any real margin because they know you'll blow your initial balance anyway).

That's what I've gathered really after studying all those guys flexing on YouTube, Instagram, Etc.

Because with leverage and volatility gives the impression that profits can be extreme. This can be the case, but for the average joe, you will be swallowed up whole. These Forex-type trading academies prey on the average joe and promise astronomical returns but most fall short.
