Sure, and I’ll even broaden that. I’m pretty sure everything that has ever been used as a medium of exchange has been used in a scam somewhere, and the easier it is to use that medium of exchange, the more scams have been perpetrated using it.

Janet Yellen is not in charge of the United States money supply. You’re thinking of the Federal Open Market Committee, which is comprised of the seven members of the Federal Reserve Board, the president of the New York Federal Reserve Bank, and four of the eleven regional Federal Reserve Bank presidents on a yearly rotating basis.

And I’m not sure why you’re bringing up a criticism of our collective net worth on a discussion around whether Bitcoin is used in scams, unless you’re trying to push the narrative that traditional fiat currency is somehow worth less than an unbacked security. Which is both irrelevant to the conversation, and a pretty good indication that you don’t really understand how currency works.

Depends on where you are.

I’m in the Midwestern United States now, where summer is often pretty frustrating due to the high humidity. But I’m originally from Phoenix, where I really enjoyed summer (in the shade), because I love the feeling of warmth soaking into my bones, and I never got sweaty.

I run those calls through my own phone system, which I host on a system in my basement. There are a couple main options out there, I used FreePBX for a while but now I’m using 3CX. They don’t require a ton of computing power-- mine runs on a virtual server inside a larger system, but you could run one off of an inexpensive thin client from eBay if you wanted to.

I get my phone number from VoIP.ms, which is pretty inexpensive and has worked well for me for years.

For a phone, you can either use a soft phone (an app on your computer or smartphone), or use an older IP phone off eBay (which is what I do since I also have a Plantronics wireless headset that connects to it).

It’s pretty easy to get started, but you do need to make sure you’re configuring everything correctly since selfhosted services can open up security holes in your network if you don’t know what you’re doing.

This is why I always record calls with major corporations when I’m talking about money. I’ve never had to actually resort to sending them recordings, but I have used the “Well, every call made from this phone is recorded, so I can go back and pull the recording of what I’ve been told if you don’t have it in your system” line a couple times.
