Yes, it is possible for you to start trading forex with as little as USD$100. Many brokers like TMGM offer trading accounts that allow traders to start with a small initial capital.

Forex trading offers some unique advantages:

a). 24-hour market
Enjoy the convenience of round-the-clock trading with the forex market. Unlike stock or commodity markets, it operates 24 hours a day, five days a week, allowing you to trade at your preferred time, whether it's morning or night.

b). High liquidity
The large trading volume in the forex market represents high liquidity for traders. This also means there are a large number of buyers and sellers at any time of the day. So, under any usual market conditions, you can instantly open or close your trade.

c). Low trade costs
Forex markets typically have very narrow spreads – the difference between the bid price and the ask price and what a broker will charge. This reduces the costs you incur for your trade, leading to potential greater profit margins.

d). Leverage
Traders have the option to utilise leverage, which allows them to amplify their trading potential beyond their initial deposit. Leverage enables traders to open positions in the forex market by providing only a fraction of the total value of the position upfront.

Leverage is a tool that allows traders to control larger positions using a smaller amount of capital. This is usually expressed as a ratio, such as 1:50, where the first number represents the amount you can control, and the second number represents the capital you have.
To illustrate this concept, let's have a look at an example:

Imagine you have $100 and use a leverage of 1:50. With this leverage, your $100 investment can control a position valued at $5,000. This means that you can potentially take advantage of the price movements of a much larger position than you could not have accessed with your initial capital alone.
