Well, just accept it as it is - it will likely in hindsight turn out to be a blessing in disguise.
We will probably have to wait till June, possibly a couple of months longer, until we hold the 8K in our hands. Nobody knows if the bitcoin frenzy has ebbed away by then, but at least we have a chance, and I doubt that it get much worse than it is today.
However, in any case we may expect NVidia to have released their new Ampere/Volta GPU's in summer, so if you are forced to overpay, you at least will be doing so for a graphics card which will be performing some 20-30% better than the current high end cards.
I wonder, if the Titan model sees the same boost in pricing as the Ti models have seen, or if that would rather only affect the 1180/2080 model - with a proper 8K in your hands, you might think about for once actually spending the insane amount for a Titan at release just to get the maximum out of the 8K. The Ti will take some 10-12 months more before it is released, and the boost offered by the 1180/2080 over the 1080Ti will be nice, but not that dramatic. But still, you would get that increase in performance for the same money and quite likely it will still arrive in time before you receive your 8K...
