Perhaps one of the main reasons for bitcoin is a decentralized currency, meaning that no one or government can control it, this means that if the government can not control it, the government will not like it because it does not benefit the government. for example, the government can not get tax money from all activities that use bitcoin. and in my opinion not only bitcoin currency that is not trusted by the government. all cryptocurrencies may not be trusted by the government unless they have been adopted by them.
