What do you have in mind what this influencer's motive?
Its true that there is no real update from Goldsach and Barclays Bank.
I did some googling since I have not subscribed to FT as well and found out about Alan Howard from
this link and he is behind Elwood Technologies.
Howard joined fellow moguls including Peter Thiel and Louis Bacon in May to put $10bn behind a new cryptocurrency asset exchange, Block.one. He is also an investor in the Sweden-listed digital asset manager Coinshares, and crypto custodian Komainu, which is backed by Japans Nomura bank.
I think this is the news you are looking for.

Confirming its real is hard to know. ethereumworldnews.com doesn't look like a good source.
