| within the blockchain. 1 BTC will always equal 1 BTC. This is why
| currencies are so far the only thing you can actually use with a
| blockchain.

| However, that doesn't mean you can trust the exchange rate
| (obviously, given Tether, but also, exchanges) or that you can
| trust the person you're transacting with. Or that you can trust
| the other actors not to scam you, steal from you or otherwise
| negatively impact your relationship with the blockchain. Or that
| you can rely on the legal system for remedy. Or that the key
| holder is the rightful key holder.
|
| Further you can't trust that everyone else will regard the
| blockchain you're using as the source of truth (See: every fork
| ever).
|
| Blockchains are an interesting thought exercise but ultimately
| achieve, literally, nothing. Certainly not in a way that's
| better, faster, or more efficient than a centralized store.
