DeMark invented the DeMark Indicator, which some traders use to time the market.
Cramer reviewed the daily chart action for bitcoin, which peaked at around $65,000 in mid-April.
DeMark, who said the drop in bitcoin resembles the crash of 1987, projected that the decline could bring the token’s value to a floor of $32,000 — or $24,000 in the worst case.
“If DeMark’s right, you could get a chance to buy bitcoin in the not-too-distant future, and I might take it,” Cramer said.
As for the S&P 500, which closed at a record for the second-straight day, DeMark’s indicator suggests the index could be close to a top, Cramer said.
