Just finished the first half - a fascinating read.

Looking forward to purchasing the full book.

Hoping for more history on the variants that came from the block size war (noting that you've only released up to 2016).

Some feedback:

• In my view, some of the fiat-price history data points could be removed, maybe 10% of them.
• I'm not sure about the vertical end-of-year fiat price charts
• All the screenshots are great - of now defunct websites etc. Maybe more screenshots of the bitcoin client, etc? A screenshot what it looked like to mine a block?

Sent some dog money -- keep up the good work.

I wish had some constructive feedback, but so far I'm just enjoying it all, especially the side-bars.

Fun fact: I interviewed for Jed McCaleb, but on his earlier project, eDonkey2000. He's a sharp guy.

Really enjoying this.

Cleanly written and it doesn't get bogged down in minutia.

Apologies if this is mentioned elsewhere in this thread:

How can I tell if my node supports the taproot upgrade?

Just to say that I received my Full Package and Standard Unit.

They are both up and running and contributing to the slushpool.

I had to reboot the Full Package before it would see the hashboard from the attached Standard Unit.
If that is required, consider adding it to the instructions.

Great experience, love the products, keep up the great work!
