HODL is the smart play. I sold off a chunk of them late 2016 and early 2017 since premiums were really good. Now that premiums are so low I have been buying them up faster than I sold them. I think Cas coins are slightly undervalued currently. Once the real coin collectors get into Bitcoin and research these coins I bet we see some crazy fiat sales.
Ditto ,
Sold goodbid and converted to fiat in late 2016
Regretting a lot !
HODL
