What's a realistic 10-year target price for BTC?

I see a lot of wishful thinking like "it's going to go 1,000x from here" but none of it seems based in real math.

Does anyone have a strong understanding of this stuff who can help me out with just a rough estimate/guideline of what BTC price could get to in 10 years...

...Assuming people keep buying these ETFs at a reasonable rate.

...Assuming some people start to allocate 1% of their retirement accounts to this stuff, etc. (which I think is reasonable, no? If not, please correct me).

I'm just trying to get a sense of where things could go price-wise in a normal/likely case. Not the most bullish/optimistic case, but just a case where things go reasonably well and nothing falls apart or goes horribly wrong.
