I had a funny idea but I am guessing it is not practical. I think it would be fun to attempt to exchange one cryptocurrency for another, starting with BTC, and going through many (at least a couple hundred) other alternative currencies, with no repeats. But I'm thinking it would be hard to trade one smaller alt coin for another, and I think it would be kinda boring to exchange back to BTC or USD at every step too, cuz that would be too easy... I'd be willing to exchange between an alt coin and some physical goods to another alt coin perhaps. Any ideas on how something along these lines could be successfully attempted?
