By the logic of some of the idiotic maximalist comments in this thread, once gold nuggets were dug out of the ground there was no further need for diversification - not minted coins, not account based trading, not paper notes and not lightweight metals. Popular music need not have bothered itself further after the Beatles. The sovereign bond didn't need to be hedged by equities, commodities nor currencies, Fine Art investments were all "scams" after Da Vinci.

Don't you nuttheads get markets or what ? The whole point of them is that they're not tyrannies. There is diversity to address everything from taste to hedging requirements to technical deficiencies and vertical sectors.

Without diversification in the crypto-asset market bitcoin would still be in 3 digits.
