I might be wrong because the website I used to lookup the WHOIS info (whois.net) might not of been updated recently.

However using https://whois.icann.org/en/lookup?name=SATOSHIDICE.COM

Points out that Updated Date: 2017-04-06

Comparing the two infos the nameservers were indeed changed so I was wrong before and looks like the domain name got sold privately.

Old nameservers
