Say, someone wants to buy 2nd hand ps4 from someone. Why would he be so eager to use cryptos with anon feature and hide his transactions?
There's always been the chance of governments attempting to outlaw cyrptocurrency outright. If they don't do that, they might also attempt to kill it with overbearing regulation, or according to Anonymint, confiscation. People see anonymous coins as being a safeguard to both of those variables, amongst others. Purely speculative on my part of course.
