Do some research and acquire domains based on future innovations, liquidity (LLLL.com, NNNNN.com, One Word, etc.), brandables, etc.
Set up a landing page on your future domains for inbound leads (bodis.com, undeveloped.com, etc.)
List on all non-exclusive marketplaces for maximum exposure (GD, Sedo, NP, Flippa, Afternic, Undeveloped, Uniregistry, eBay, etc.).
Good luck my friend!
