I love me some cryptocurrency, but I also like putting back some metal.
Nothing against gold, but I prefer keeping my metal in "small change" quantities (silver spot price at the moment is $24.25 per ounce and my holdings are in one-ounce and five-ounce increments) to something that goes for (as of today) $1,833 per ounce. That's more flexible both in terms of liquidating a portion for fiat if I want some, but not a lot, of "money," and in terms of using as money for everyday needs if, as some are always predicting, the economy collapses and fiat becomes worthless.
Not, mind you, that I've got a half-ton of the stuff. We're talking three figures as expressed in Federal Reserve Notes, much of that bought in one or two ounce increments over the years, across vendor tables at conventions, etc.
But anyway, I recently received my first order from APMEX (not an affiliate link) and have since placed a second order. Good selection, good service, fast delivery, and reasonable prices (obviously you're going to pay a premium over spot; on the other hand, shipping is free for orders of $200 or more worth of metal), and they accept cryptocurrency (via BitPay). So if you're looking for an online, crypto-accepting metals source, take a look there.
One interesting find: A silver version of the gold coin that appears in the John Wick film franchise (yes, they sell the gold version too):
