Whenever money is involve, there is always a place for it to be traded. I mean if there is no trading, then it is for free and that people will either abuse it or does not care at all. Think of bitcoin right now which is not trade-able, do you think Satoshi Nakamoto will invent it in the first place if there was no purpose? You know nowadays that MONEY TALKS. If it does not have any value, nobody cares of it. This is what I see if cryptocurrency cannot be traded.
