As you will see in the email quoted above, he mentions some HODL coins, but the dips,

Hold On for Dear Life

But he is trading what are classified as 'shitcoins' and that includes Bitcoin ;) He only ever has Bitcoin for buying other tradable coins. From the email, Stan had said HODL these:
ETH
DGD DAO (digix digital Gold, physically backed)
ADA (Cardano)
STEEM
He's holding Cardano but swing-trading portions of it to add more.
