He (Tidjane Thiam, Credit Suisse CEO) said this at a press conference call on November 2, 2017 when Bitcoin's price was hovering at around $7,3k.
His verbatim quote:
“From what we can identify, the only reason today to buy or sell Bitcoin is to make money, which is the very definition of speculation and the very definition of a bubble.”
It's pretty hilarious to see all these banking CEOs and their anti-crypto quotes from just past couple of years shitting on crypto and then being embarrassed just by actual events in very near future.
And on other hand his banking firm that he's been CEO of has been awfully managed for years which can be seen just by looking at that constant downward chart of their stock, constant YoY decrease of their revenue, net income and assets under management, and the fact that just few months ago it almost completely collapsed and had to be sold for a very low price to other investment bank in Switzerland in a deal that was finalized this month.
If you bought $1,000 of Credit Suisse Stock and same amount of Bitcoin at the time he said this and didn't sell, you would right now have around $50 worth of their stock and around $4,350 worth of BTC.
