If you will allow me to play devils advocate. I have very little faith in the mental faculties of my fellow man. Consequently I find it hard to believe that dash failed to gain traction on the darknet markets it was introduced on as a result of any sort of technical understanding on the part of market actors. Meaning, to most of them, monero is going to appear indistinguishable. What reason do we have to believe a private currency will gain traction this time when it failed last time?
Because 2 years ago it seems virtually all btc users thought it was anonymous enough and now there is a significant % that realize this is not the case. Now there are companies whose sole purpose is tracing btc transactions. It seems even mixers are vulnerable.
I guess the means having a little faith.
