I want to invest in or invent a male-only currency, for fun. Does it exist, can it exist?

I'm fairly certain that bitcoin was primarily a (male) nerd currency for a long time, and, regardless of the intrinsic worth of a bitcoin - it appreciated in value against fiat currency (which, supposedly, is driven by consumer spending, which is +70% female). Men earn more and are taxed more, while government outlays are lower for men than for women.

So... what if there were a male-only currency?

I don't mean "respect", like how the respect of men is exchanged for deeds done - I mean a bonafide currency with exchange value.

Engineering a male-only currency would be challenging, but you could link it to a male-dominated field (like with bitcoin was to computer programming/cryptography - being largely male interests).

With biometrics and cheap technology, it wouldn't be impossible to implement a system that can sort men and women in a database.

If men are the ones that are truly productive, and if women drain men of resources, then a currency that can only be used by men would appreciate in value because women could not spend it.

When women start using bitcoin at the same rate as men, I doubt they will add much value to the currency, and it will plateau... but an index fund of male labor - that sounds like true value-based-investing.
