As far as hashflare goes I am sure that they will implement the lightning network eventually. They seem optimistic about layer 2 solutions. This will, of course, benefit us all in terms of bitcoins medium of exchange aspect. Much lower fees for the users, faster transaction times etc. I have more documentation on my website about the lightning network if you are looking for more information on that subject. https://www.eliteblockchaincoalition.com

Btw I did not organize the interview. I do however have permission to share it. Hope the information has helped you.
