Now is a definitely good time to buy coins at a low price, if you buy now, you will get good profit when the market recovers.
I agree that these days is a good timings to purchase those altcoins you had, because it's at declining value now. But be careful on picking those prospects, you might choose slow rising currency. The trend can be so tricky, you might fall into shitty coins in which could die in a long run of day trades.
