From the Coin Telegraph:
"SingularDTV has announced it has hired noted Hollywood producer Michael Blieden as an advisor.
The firm, which is working on multiple projects and utilizes Ethereum technology, is due to launch its flagship product in Q2 this year.
Blieden will be a major contributor to the event and will receive his salary in Ethereum tokens." Why not paid is SNGLS shares instead, gives him more incentive to work harder for Singular. Ether price will go higher regardless.

May be because the only SNGLS that are available for the
Workshop (be used for development of the platform) are locked for 2 years from the date of the ending of the token launch (Oct 2018). SingularDTV did raise ETH in that token launch. Since it has been selling some or that ETH they have fiat (usd) as well. So the choice is simple:
ETH or USD...
Fair enough Blieden went for ETH
