Try looking into:
StackCoin - This one was epic back then
one of the first ICO's held on bitcointalk.. NO escrow
USBcoin - I lost some serious money on that.. Dev created a workaround in the code to add new coins into the blockchain. In 3-4 hrs of trading on bittrex he made over 60btc
Of course Paycoin drama lol
Maybe the subject ICO coins itself is a good thing to read about for people
And what do you think about all the exchanges which went bust?
Coinmarket.io
Mintpal.com
CryptoRush.in (1st version)
Bter hacks
Also positive things of course.. How poloniex got hacked and paid back every penny to their traders, and is still a well respected exchange etc.
Good luck with the book! I was wondering for a while why there wasnt one written yet..
Cheers
