Quoted for posterity. Won't it be wonderful to be ridiculed for that one day?

More than wonderful and would totally welcome that ridicule... but at the rate BETI is growing daily I am pretty sure it has already reached escape velocity.

It doesn't work like that. It would converge on a stagnant price, because it's using a best-fit to a model.
Output of a hacky script to do this today gives this:
a: 0.00270185020127701
b: 0.572820201440624
predicted y: 10.7831121120664
predicted price: 48199
Oh.. ummhh... I reckon I donno what I am talking about... I just used the formula link the OP posted some time ago. I thought that was ok to just run it to update the price.
Thanks for the update! And yeah, if that is the expected price nowadays and it doesn't run away as I thought then it is perfectly possible it will be crossed sometime.
