What do you think of these hashrate tokens? The first batch will be sold in minimum lots of ~275k$, so it's only for whales, but they will be traded OTC in 0.1x lots. What looks nice to clueless me is they sell at a discount to actual mining hardware. And, more importantly, the buyer is not subject to issues with delivery, operation, maintenance etc. of actual ASICs.

Are they a thing? Can they become a thing in due time?
