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?
