Why not? I farm Greens, then Blues, then Red's and finally cash. I never have to worry about finances and as a token buyer I can also compete comfortably in bidding wars. When my bidding opponent sees my financial muscle I reckon that gives me an edge and I rarely need to go past 10 tokens in a bidding war.
Each to their own as they say.
