Answer
$100 can open a micro account but barely covers proper risk management. With 1:30 leverage, you control about $3,000 yet a 50-pip stop risks 50% of capital. Realistic expectations mean tiny profits or learning losses. Use it for platform testing, not income. Scale up gradually with proven strategies. Most pros start with thousands. $100 teaches discipline if you risk 1% max per trade but won't sustain living.
