A recurring thesis for spurring on that economic activity, supported by continued investment from crypto funds and ICOs, is the emergence of stablecoins. The argument goes that if you have a virtual currency that stays pegged to the US dollar, for example, then the currency can be used to buy and sell goods without the fear of volatility (or capital gains on buying a sandwich)... And if we can figure out how to dampen volatility in the markets, perhaps that will also be seen as a positive by the SEC. A lot of ink has been spilled on how different projects are different -- but at the core, this is an automated macro banking algorithm that must maintain price parity, backed by assets, leverage, or fraud. One that can be manipulated or broken (e.g. below, Nubits).
