No one exactly knows when will the current down trend will end. It might last until March or April and this is what I think also. There is a great resistance at the moment that's why we keep on seeing the market bloody. The trend started on late December and lasting on March or April is not that bad.

Why do you think the price keeps on decreasing? Because many are selling even though the price is so low. So we must hold our coins. Will cutting our losses will do anything? None. Well it will make the price decrease even more. Cutting losses is just like feeding the whales and don't ever feed the whales.

AFAIK, you haven't lost anything yet unless you sell your coins at a very low price.
