Different reasons for different people. There are several camps of BitCoin haters:<p>(1) There are people who think it&#x27;s a pure speculative bubble or pyramid scheme. (I disagree because it has utility.)<p>(2) There are also people who point out that it&#x27;s a deflationary currency and therefore broken. (I sympathize a bit with this view but it&#x27;s not enough to make me dismiss it completely. I think this might be a solvable problem.)<p>(3) There seem to be some who just take a contrarian position against things that have received a ton of hype or that are too fashionable.
