It's not for me. The whole point of investing in domains is to have the flexibility and control over when, why, how, and for how much I can sell these digital assets.
Micro-ownership eliminates all of these advantages and also introduces a pile of negatives.
For example, let's say you invested in a premium 1-word with 100 other people, and (what you think is) a great offer comes in allowing a massive ROI that would really help you right now.
It's put to a vote and your side loses 60% to 40%... so you make $0 and you can't sell your portion back at the offer price, so you're stuck and could be stuck for the rest of your lifetime. Or even worse, there could be a lowball offer that you totally disagree with it, but the economy is bad and a few big investors need to get their money out so again you lose the vote 55% to 45% and your investment ROI tanks.
No control = no way.
