Many people hate bitcoin because they haven't studied the technology deeply enough. In their minds, Bitcoin is no different than a Ponzi scheme, so many of them don't even try to study Bitcoin. Only by studying Bitcoin technology can you realize that it is not a Ponzi scheme, but a peer-to-peer electronic monetary system that is independent of third parties such as banks or the Federal Reserve. In addition, Bitcoin allows you to maintain your privacy, which is a huge advantage over national currencies.
