The IQ Option real account requirements are slightly different in comparison to the accounts of other brokers. The minimum deposit is as low as it can get; $10.
The lowest possible investment is only $ 1, so if you wish to trade small amounts you are free to do so.
The advantage of these very precisely adjusted investments is that you can easily follow your money management strategy which is very hard to do using other platforms that usually require a minimum deposit of $100, $200 or more.
