Investments in currencies have always been in the attention of traders because of the advantages of FOREX market: high volatility, liquidity, requirements for a small start-up capital, no additional fees and around the clock work of this market, add to this quick transactions and you'll receive probably the best tool for investing (do not forget about risks). The currencies' prices change every second, which means the opportunity to get profit from market fluctuations all around a clock (except week-ends and some holidays).
