States are getting more sophisticated at tracing crypto coins.
And getting anything useful from them does depend on states not regulating them into obsolescence or black markets, with all the baggage those markets entail.
As for pettiness, I'm not the one promoting dubious benefits, nor am I invested in any coins or their downfall. Just concerned the whole thing is making the world worse: more gambling, more corruption, more scams, more wasted energy, more pollution, etc.
Also mining will come to an end soon as it becomes impossible to meet the energy demand.
