Isn't the author's statement here moot? Capital investment allows spending - assuming the recipient needs to spend the money; giving $1,000/month UBI to everyone 18+ years of age, you can bet 95%+ of them will spend it, it won't sit in a bank account, and it will lead to an ROI - even if that's personal development or quality of life improvement that will have cascading, lifelong productivity benefits to (including counter counter-productivity).

Does this author have vested, financial interest-motive in Bitcoin or other crypto-"currencies" - which centralized digital currencies (legitimately fiat, a better transparent version of)?

Edit to add: looks like they likely do, re: a project they list in this site's menu - oh, and in their about me: "Early Bitcoin adopter, now Bitcoin Cash supporter." Would it not have been best practice for the author to list their vested interests as they're writing about a competing product/offering?

Imagine if everyone countering the positive narrative (propaganda in part) perpetuated by the "army of HODLers" was financially incentivized to counter that narrative whenever they had a chance, and not only that but proselytized their position, Bitcoin et al would have never reached its position today and many people who bought into the hype - or even killed themselves because of their losses - would have not unnecessarily, unreasonably transferred their wealth to someone else; a true centralized digital currency could take the cash you transfer into the digital currency "out of circulation" instead of giving it to someone, Bitcoin et al similarly structured - the "army of HODLers" are akin to a religion that's financially incentivized - even Fred Wilson - https://avc.com/2019/04/orthodoxy/ - stated he dislikes the cult-like behaviour of some in their community, without realizing he's in the community but just taking a priest-like role where he's in a more refined position and better controls his behaviour/image.

I am glad higher profile individuals are starting to voice their opposition, dislike of Bitcoin et al - Elon Musk recently tweeting out "Bitcoin is almost as bs as fiat money;" https://twitter.com/elonmusk/status/1340588909974200321 - fiat currency can shift into a better system supported by immutable, transparent blockchain - but with centralized control so no shenanigans can occur hidden from other allied nations you're trying to fairly balance economies with, arguably who will all be democratically elected governments, democracies.

Edit to add: With the growing "army of HODLers" with more vested asset holders waiting for the value of Bitcoin et al to recover and then some - while chanting the mantra "HODL!" - we need to pay attention to counter regulatory capture that this newer industrial complex will work towards.
