I think you're absolutely right. It would be unrealistic to think that efforts won't be made to demonize cryptocurrencies and try to scare people away from them. Already there is a bill on the docket, The Combating Money Laundering, Terrorist financing and Counterfeiting Act of 2017. How ironic since the world's central banks are the biggest counterfeiters and major commercial banks have been caught red-handed repeatedly laundering money for drug cartels. They're going to try and make it difficult, frightening, and even illegal to hold cryptocurrencies.
Yet that's all the more reason we need to have them. Just ask anyone in Venezuela or Greece who's only means of survival is Bitcoin. We just need to hold on----it's going to be a bumpy ride!
