You know what? He is not wrong.
The last 3 cycle tops that we had. They had one thing in common. I had friends and family buy crypto who never knew what it was. Then usually a month later, it topped. Each of the 3 cycles I noticed this. Maybe it was a coincidence.
But you need to understand that it’s not only the crypto markets that are stretched. So is the stock market. Look at Nvidia today at earnings. It beat estimates but stock dumped anyways after 5% because it hits of a bubble.
People buying BTC suddenly despite the fact that they were never exposed to crypto in the first place can be a signal of the bullish top.
But we've got such thing going since the first day of ETF, literally people who never buy BTC is buying BTC through ETF so I think that kind of reason become invalid these days.
In fact, current rally largely motivated by ETF inflow.
