I think it is correct to say there is high risk involved when using high leverage.
But of course, trading is risky to some degree no matter what form of trading you do. Whether you trade with or without leverage, it is possible to trade in a smart way, managing risks well, or in a silly way, losing more than necessary.
However, the point of leveraged trading is amplifying your gains, but if you think about it, your losses will be amplified, too. If you don't have experience, experiment in a demo account or cent account first, and avoid doing real leverage trading until you are confident you can be profitable. Make sure to learn how to place orders, especially stop loss orders correctly, and when choosing a broker, be aware of their liquidation policies.
