@newstik Bitcoin, like a physical commodity, and unlike any other financial asset, is 100% *non*-derivative. The mentioned ETFs are backed by actual BTC and audited for it.
The U.S. gold reserves on the other hand, one of those nasty conspiracy theories I'm sure the author would state, have not been properly audited in half a century now. The last available report is from 1974.
But hey, gold was a bad idea anyway, according to that author. Let's just print more dollars!
