My current strategy is simply buy and hold Ethereum, Lisk, Stratis, & Sia. MaidSafe, Komodo are also ones to watch.
Ethereum, Lisk and Stratis are defining the shape of future blockchain development.
They won't crowd each other out either - there's room (and a need) for more in this space.
10x within the next year. When the C# developers start picking up Stratis, and the JavaScript developers go mad for Lisk, we could be looking at 100x down the line.
This page nicely shows the potential, in terms of active skills, that will be let loose on these platforms when they fully mature:
Those are my thoughts on it. I'm interested to here alternative views!
Have fun,
