According to BlockBeats, on September 12, Deutsche Bank said that American consumers' interest in cryptocurrency is heating up, with less than 1% believing it is a "flash in the pan," a significant drop from previous years.

Just over half of those surveyed consider cryptocurrencies to be an important asset class and payment method, and 65% said they believe cryptocurrencies could replace cash.

The bank surveyed more than 3,600 consumers in the U.S., U.K. and Europe in March and July. Analysts Marion Laboure and Sai Ravindran expect the democratization of cryptocurrency to advance further in the next 2-3 years, driven by ETFs, Fed policy and regulation.
