How many XLM do I need to be a millionaire?

I'm curious about something related to cryptocurrencies. Could you please help me out with this? Given the current market conditions and the price of Stellar Lumens (XLM), how many Lumens do I actually need to own in order to become a millionaire? I'm trying to set some financial goals for myself and it'd be great if you could provide me with a rough estimate. Of course, I understand that the price can fluctuate, but just a ballpark figure would be helpful. Could you possibly give me an idea?
