1. 50.1% attack

Read the whitepaper!

A 51% attack to double spend would be less profitable than using 51% of computational power to generate legal bitcoins.

Doesn't need to be profitable. Just needs to be worth while to eliminate a competitive threat. Have a look at some of the financial institution profits... I think I read somewhere to launch such an attack would be 500 million. Its really not much in that world
