Guy Gentile, CEO of SureTrader, who called the top on Bitcoin back in December 2017, is now betting almost $20 million on a major market sell-off.

Many classic indicators are playing into his prediction, including the fact that the U.S. economy is on its second-longest expansion on record, growing for 106-straight months.

The 10-year Treasury note hit nearly three percent last week Tuesday raising issues on inflation, the Federal Reserve’s plan to continually increase interest rates, and commodities - namely gold and oil, moving higher.

According to Gentile, with all these factors at play, investor’s need to be prepared for an eventual market correction.

“We’ve seen massive speculation and excessive leverage in the brokerage firm, which are added indicators to the ones we see more of every day.”, says Gentile.

“The 10-year Treasury rate is increasing to figures seen back in 2008, and the Federal Reserve has plans to increase interest rates more.Something has to give, and it’s usually the market. Right now, this is a recipe for a 15-20 percent correction.”

With this, Gentile is watching these indicators closely every day; shorting mostly tech stocks and the SP 500 index, all in preparation for a sell-off, with a nearly $20 million bet.
