Hi ActiveTraderx50,
I have seen dozens of trading bonuses offered like this over the years and spent countless hours reading their T&Cs.
They can be an attractive way to get free trading credit, allowing you to practice setups etc, but it’s important you don’t let them encourage excessive trading and over leveraging.
It’s always worth reading the terms. As you said, bonuses often can’t be withdrawn, or you have to meet substantial trading volumes first.
The final thing I would highlight is that trading bonuses aren’t typically permitted in many tightly regulated jurisdictions, such as the UK, Europe and Australia. This is largely because they can incentivise risky trading practices.
