Years ago, I advocated banning crypto as a means of limiting the damage AI could do, thinking an advanced AI might be able to mine or hack exchanges (eg by guessing passwords of "lost" bitcoins) and accumulate wealth (ie power).
Apparent it could also just make a meme coin, and generate billions from nothing, given a sufficiently edgy coin (for example, AI itself)

I am once again humbly suggesting that all un-regulated currency, especially distributed ledgers, be banned worldwide as a precautionary measure.
Another example that reality (especially anything involving technology) is not constrained by the need to be realistic. What SF author would dare write a story with meme coins, much less one in which the meme coins involved AIs like Claude?
