During a Reddit Talk session on Thursday, "Shark Tank" investor Kevin O'Leary said that his cryptocurrency exposure is near 10%.

"I've grown the portfolio remarkably," O'Leary, chairman of O'Shares ETFs, said. "At the beginning of the year, I was at 3% weighting. The target was to get 7% by year-end. However, because of the appreciation of so many of the assets I have now, we're almost at 10% today."
