Let me advise you the way I would go by it if it was my money. First, note that leverage doesn't have a say here, your right plan towards the management of your account and money is what matters most. If you play with the money according to leverage, I don't think it's a smart idea as dangerous leverages could still be permissible with that kind of amount even if you try to lower it.

This is why I would like to first borrow the idea of DCA, I will divide the money into 10 equal parts and start risking each trade with each part. This is a very good way to manage one's account in trading, and I beat it down to 10 parts because I don't know your trading capability. For me, I can still go for 5 parts and it would be successful as it always does. However, one thing that is very important in trading is that you have your complete working trading system. This entails your strategy, management, and what keeps your psychology in check.

If the trading system is foolproof, the suggested approach will definitely work fine for you.
