I can tell you my personal issues with bitcoin.<p>1) I&#x27;m still bitter I threw all mine away. I had a few hundred in the early days and thought, &quot;this isnt going anywhere&quot;....<p>2) I&#x27;m one of HN&#x27;s resident conspiracy theorists, for lack of a better term, and bitcoin can be seen as a threat to freedom because for all the awesome things it is, <i>it is not anonymous</i>. This may seem innocuous at first, but if you subscribe to the globalist conspiracy view, one of the primary tenants of &quot;their plan&quot; involves cashless, digital only currecy easily tied to your personhood. In essence, I fear the future will be more totalitarian and dystopian than people realize, and digital currencies like bt seem ripe for abuse and use in such a system.<p>3) Along the same lines as 2, I feel like once banks start getting into bitcoin heavily, despite its theoretical mechanisms to prevent it, the banks will find a way to corrupt and control the system. The community has already experienced the first attempts in the form of the huge first price inflation.<p>4) Another problem with bitcoin is that it requires good cybersecurity, which we all know is much more rare than anyone wants to admit. It&#x27;s ripe for mass thefts. Once that wallet is gone, not much can be done.<p>Ok, thats most of it, now I have to say that I understand there are many &quot;ifs&quot; in what I am saying, but to me the threats are real. I still will use bitcoin for the time being anyway, and there are many good things about it and other *coins, but you didnt ask what I liked, you asked what I dont like.<p>On that note, blockchain technology independent of bitcoin I expect to be a huuge hit. Blockchain all the things!
