Forex is traded through a forex broker. Traders can sign up online and download one of the trading platforms onto their computer or mobile device and start trading instantly.

Forex, in general, is very much not a pyramid. The foreign exchange market (Forex, FX, or currency market) is a global decentralized or over-the-counter (OTC) market for the trading of currencies. It is very real and anyone can participate in it and make a profit.

While foreign exchange (forex) investing is not a scam, plenty of scams have been associated with trading forex. Regulators have put protections in place over the years and the market has improved significantly, making such scams increasingly rare.
Unfortunately, scams have been a big problem historically, faced by everyone in the forex industry. As with any new industry, plenty of predators exist out there, looking to take advantage of newcomers.
Forex itself is a legitimate endeavor. You can engage in forex trading as a real business and make real profits, but you must treat it as such. Don’t look at forex trading as a get-rich-overnight business, no matter what you may read in hypedup forex trading guides.
With real work and time invested, you can have a profitable, legitimate forex business. Like any other real business, though, there is no free lunch.

You can start as low as $10 but I recommend starting with a minimum of $75. You can trade micro-lots with that amount of money.
