I would not like to speculate here far too into the future or to speak about (yet) less realistic values.

I just know one thing:
Compared to the current "top" cryptos XMR has real development, a network effect due to a strong growing community and it has a utility as real money, way better then BTC or derivatives of BTC.
The current valuation of XMR is compared to other larger projects a bad joke and will result in an upward correction. This low market cap is not sustainable and will result in higher prices.
