Umm, what is the benefit for separating the isotopes? For heavy water it's quite clear the properties in certain applications are needed, but for silver and copper?
Wasting energy on something for no further benefit is a waste...
nooooo how can someone be into BTC and so dumb :-(
good money is only about being rare and hard to create; gold has very little practical purpose and BTC has none
so rare isotopes would be perfect, as long as they are not accessible via LENR synthesis path
