First, let's clear one thing up. There is NO recession, at least not yet. We are in an economic slowdown, and MAY avoid recession if we can avoid a world crisis (i.e. Sept. 11).
Now if the slowdown / possible recession has a negative effect on coin values, I will see it as a buying opportunity, as I still have a long term collecting horizon. Remember, a booming coin market may feel good, but if you are able to buy in a bad coin market instead, your wallet will feel better.
