What do you mean by "vs"?
If you want to compare the two, agriculture has the upper hand. Agriculture has a harvest cycle in which the estimated profit can be predicted even close to "certain" on a routine basis. Both bitcoin and agriculture have something in common to be profitable: you have to take care of it, and wait for it to grow. This means that the two of them cannot support each other simultaneously.

I understand this that you need capital in bitcoin, right? If you don't have enough bitcoins, invite bitcoin holders to invest in your business that can give bitcoin returns as well.
