I'm finding the state's reaction to crypto amusing. The penny hasn't dropped yet that it's impossible to track. The UK govt made some noises about 'planning a committee to launch an enquiry look into crypto in 2018'. Can you just imagine all those crusty politicians sitting round trying to pontificate? I want to be a fly on the wall when expert after expert testifies & says 'you've lost, go home'...'it can't be tracked, it can't be taxed, give up'. Eventually the solution will be no tax on income/capital gains, just stick it on goods & services.
Some of the tax cattle are leaving the herd. More will follow.
