This pretty directly contradicts a lot of the hype around Ethereum. Yes, bad contract code is bad, but a lot of money is about to evaporate. If it isn't easy to write secure contracts then there is a serious deployment problem.

This is what really annoys me about the Ethereum VM, there was no need for turing completeness. Bitcoin has a perfectly good scripting system that they keep adding opcodes to, and is not vulnerable to some of these kind of attacks.

  Could you point me to some resources showing recently added opcodes? Last time I looked at the Bitcoin code they had actually disabled some of the original opcodes due to security concerns. I'd be interested to see that this trend had reversed.

    Sorry, I should probably edit my comment to say "over the years" and not necessarily recently. I think my point was more that the conservative approach Bitcoin takes works better on the long term, and there's still proposals that slowly get implemented. I first got into Bitcoin in 2011, and since then there's been plenty of new opcodes, and as you say some original ones that got disabled as they presented risks. Latest one I can think of that got implemented would be OP_CHECKLOCKTIMEVERIFY in 2014/15 (?), but I haven't really kept up with the BIPs that much with all the infighting

  It's a giant pain in the ass to code Bitcoin. In a few years, all of these kinds of attacks will have been tried against various Ethereum contracts and it will be hardened and still easy. It will still be very cumbersome to code Bitcoin.

No money is going to evaporate. First of all, the value just changes hands and second of all, there is no money involved, just toy bits.

  Exactly, its just toy bits.. But we live in a reality so upside down, that we value toy bits and numbers on paper more than the real things :)

  well the market price of ETH went from $22 earlier today to as low as $15 in the last 30 minutes so I would say a lot of value has evaporated even if the eth itself hasn't.

    I would not consider fraud schemes valuable.

  What do you think money is?
