I think when newbies enter the live forex market, they want to book more profits with very small amounts, so leverage attracts them. But it should be kept in mind that leverage is associated with a certain amount of risk. While it can push your trades to make profits also at the same time it can put you in loss which is even more than your balance you have. When I started, I used to look for a 1:30 leverage ratio with a minimal balance that I can handle. This keeps my risk minimal. You can gradually increase your leverage ratio depending upon your earnings and understanding.
