As someone who has tried to build a simple DAPP on bitcoin, my god, this is not what bitcoin was meant to do. I mean I love bitcoin, but building smart contracts on bitcoin is like using a screwdriver to implement a calculator. Bitcoin took a route which isn't suited for things which Ethereum wants to achieve. A great example of this is Augur vs Truthcoin/Hivemind. The team behind former looked at Bitcoin first, but realized how much difficult it would be for them to build this on bitcoin so they went Ethereum route and now they are very close to their alpha, where as Truthcoin/Hivemind went nowhere.
