I contribute as much as I can. Unfortunately, my current situation doesn't allow me to buy HIVE (which I would be doing right now, taking advantage of its current price, if the situation were different). But with what I generate from my publications, I can reinvest it in different ways.

There is many ways to contribute, no one has to buy Hive. It matters what you do with the stake you are given. More you grow, the faster you grow.
