On start you'll get virtual $10,000 on a balance. You can't withdrawal it as the real money but you can refill this sum as much as you want to try the IQ Option trading platform opportunities.
All new traders start with a Practice account automatically.
WHAT'S THE DIFFERENCE BETWEEN PRACTICE AND REAL ACCOUNT?
The only difference is that you are not trading with a real money.
As the charts on the Practice and the Real accounts are identical, you may plan your strategy and test it on the Practice balance, before you invest your real funds. You can experiment with different assets, different trading time, various investment amounts etc.
KNOW THE RISKS OF TRADING
There is no actual monetary risk when trading demo. But trading on a Real account is a completely different story. Since you are investing your hard-earned money, losses are going to hit much harder. This, in turn, can negatively impact your trading confidence and lead to irrational decisions. Accept that losses are a part of trading and plan for them accordingly.
