I'm skeptical that Bitcoin's value is strongly related in any way to Tether. The larger meta-Bitcoin point, though, is that although nobody can print Bitcoin at will (because it's open and auditable, unlike the printing of dollars) anybody can create their own cryptocurrency and print that.
On the other hand, everybody knows that, so Bitcoin's so-called "market cap" is several times bigger than that of all the other cryptocurrencies put together.
These services are implemented in different parts of Fastly's production stack, but they share the same global infrastructure footprint and a lot of the same people/teams are involved with both.
would that be true for providers that aren't Fastly? why would there be a different implementation for non-fastly? or are they the sole providers for private relay?
Because the ops org doesnt concentrate on just the one application. They have broad knowledge of the entire stack and therefore don't have as deep of an understanding on any single piece.
The dev org also doesn't concentrate on just one application. I've not seen this situation where every Ops personnel is assigned to the entire stack. Each Ops employee or team in a larger organization is generally responsible for a subset of the environments.
They're not counterfeiting Bitcoin, just the means to prop up it's value. The big difference is the printing of Dollars is open and auditable.
