Agreed, perhaps coins that have utility will be impacted as well, but due to the fact that they generate utility and have low to no transactions fees they will stay alive until it becomes more and more accepted up to the point that the U.S. Dollar and the EURO will have to bow in front of this new "internet-cloud-based" currency that is immune to any territorial/country jurisdiction and hence reducing the likelihood of these so called "developed countries" to impose sanctions and monetary restrictions over other weaker and smaller ones.
