I watched the documentary that was narrated by Keanu Reeves. The arrest seemed totally illegitimate and many security experts called the government explanations horseshit. The first thing I always notice is the flaws of a system. So data-mining was pretty much the first thing that came to my mind.
I did notice Zcoin as I check coinmarketcap several times a day. I still have higher hopes for zPIV in PIVX. NEM finally made some moves some time ago and so did Komodo. So PIVX should soon make some big moves.
