I think the method should be decided first.

If you double $10M 7 or 8 times. Then, your playing with some real cash. But, you can't do it sloppy markets.

You can buy a futures market and add. I've seen people do this. Can work.

Can buy LT options and sleep well at night. Buy at a buck sell at 30, 40, 50. This would require more than one trade. But. I've done this percentage on options before so....

I don't know if either of us have the mindset to trade our way up. I always have a hot streak and then start maxing all of the bets just like you. That does not work out. At least for me.

What other method can you think of?

I think buying a futures position and adding is solid if the right market can be picked.

The LT option play is sound and stress free. I have seen people work that out. Interest rates come to mind. As well as some commodity producers.

What do you think?
