Agree it’s not that informative - was hoping someone on the forum might know more. I suspect the intention is deeper than just accepting/processing bitcoin as a payment option. Thanks.
If you want to know about this, there are plenty of good articles/ tutorials/ YouTube videos on hardware wallets, or BTC in general - the
original Satoshi paper is actually best, but there has been plenty written about that is excellent too.
The issue is decentralization of BTC - if it is held in an exchange (like the USD is really held in digital form at various banks, all 'guaranteed' by the Feds), then it is no longer a BTC; it is a certificate from said exchange that you own so many BTC. Just like gold certificates aka shares in GLD etc.
You only need that "proof" that you own BTC and it is in that long set of digits representing the decentralized/ shared public ledger, and it can be either a long paper printout (not really practical), a USB flash drive ... of better, a "hardware wallet".
The right way to do things is to keep some BTC in an exchange, and hold the bulk of it in a hardware wallet; Jack knows this perfectly well.
There are a few reputable hardware wallet suppliers. Having SQ create one would be huge.
As an aside: just like
Tesla has its hugely powerful entrenched enemies, BTC has its even more powerful enemies, namely the Federal Reserve apparatus, basically all the t
raditional banks who haven't done much for the economy* (an
euphemism).
(*) In short: buying up real resources from "free" money given as loans they do not intend to pay back. Free as in paid for by taxpayers, aka you and me. If you are wondering how the --- this is all going to end, welcome to the club. Sometimes I wish I didn't know what I know - but then there is always the possibility I'm wrong. At least Tesla is doing something useful/ right, so I have that to cheer me up.
