Three reasons make forex attractive. First, liquidity: on majors, you can enter and exit without moving price, even with a few hundred thousand euros.
Second, accessibility: you do not need huge capital to start — a standard account works from a few hundred. Leverage lets you open positions larger than your deposit (with the matching risks).
Third, 24/5 coverage: you can trade before work, in the evening, at night. But that flexibility traps anyone who does not set their own hours — discipline replaces the opening bell.
