do you know that some time ago steam accepted BTC as a payment?

Really!? Valve ought to bring that back, given how much more popular Bitcoin is becoming. It's sound money and the last solution to many old problems that fiat always seems to have.

The way I do it, I buy Bitcoin through a safe exchange, such as Gemini.. once I have my Sats, (which is the lowest fractional part of a Bitcoin) I transfer them to my preferred wallet. Then I just sit on what I have, or what they call, HODL.. cause my goal is to have viable currency after the fiat system inevitably comes crashing down from its own stupidity.

HOWEVER, it is possible to buy some things with Sats (Part of Bitcoin)... About a few months back, I bought some old books from my younger brother using my Sats, that way, he had some of his own and I had books to give my students. As more individuals use it, as well as companies, it becomes more viable and secure.

I HIGHLY recommend signing up on MeWe and joining this Bitcoin group here:

The owner taught me just about everything I know and I'm still learning stuff. And we have a LOT of fun smack talking about Fiat currency.
