Perhaps with rising interest rates people will do smarter things with their money rather than chase unpromised profits from these speculative instruments.No I can't. But look up Dutch tulip mania, they drove up tulip bulb prices to the point that you could buy a house for one bulb. These were not entirely valueless, you could plant it and grow a bulb, but people became convinced (up to the day the "bubble burst") that these bulbs would just become more and more valuable indefinitely. I view this similarly.
