"And by holding on, you are saying that going forward, this is the best investment you can find -- you have the best odds of making money in RVX vs all other stocks out there.  True?"

What I described was a case of almost total loss (not uncommon with RVX) which doesn't give you a lot of cash to put elsewhere to gain. It might be deemed that an investment at this extreme low price might be a very good investment. Had you invested a bunch a few weeks ago in RVX at $0.23 and sold at $0.35 in a week, that would be considered a good investment. Holding today is like making a new investment today at today's price. The old investment is basically lost. Yes, the tax loss is a possibility if that is where you are but these are all decisions each investor has to make. There isn't a hard and fast rule for all.
