According to BlockBeats, Wintermute co-founder Evgeny Gaevoy said at the Token2049 "Institutionalization of Digital Assets" roundtable in Singapore:

“To some extent, the passage of a spot Bitcoin ETF was inevitable and it was going to happen sooner or later. I think what people may have misjudged was the timing because even if the SEC eventually approves all of these products, it will still take some time for them to be listed, approved, and then some time for managers to distribute.

So it's going to be at least six months before we start to see money flowing into these products, but more realistically probably one to two years. But like I said, it's inevitable eventually, so I guess it's bound to happen. It's hard to say how much the price will be affected from that perspective, but I think once we see real money flowing in, that's when we'll get back on track with substance."
