Very good analysis.
We need to remeber that, while hodling coins can be prefectly legitimate, if we can't imagine doing anything other than hodling a specific Altcoin, it's probably not going to be around in the long run.
If it's got no actual use, the only real uses left are storing, laundering, and otherwise moving money around.
I, for one, wouldn't bet on EVILcoin to hang around (if it isn't already dead... last time I saw it was several months ago) ;)
