The reason I can’t buy bitcoin is the exact reason I want to buy bitcoin

I went to deposit funds into btc-e.com, my international transfer was refused because it was deemed 'too risky'. Despite explaining to them I've dealt with btc-e.com many times, for larger amounts, they won't budge.

Reason behind including the nonce in the block header?

I’m wondering why the nonce is included in the block header, and thus in the prevBlockHash of the subsequent block, etc. What would break if you didn’t do that?

It seems to me that you would still be (a) able to validate the block, and (b) unable to mess around with the transactions in the block, because that would modify the hashMerkeRoot field, and thus render the block invalid.
