Absolutely, there is no need for the rush. Much is not gain at the moment so why do you worry yourself that much by selling your coins now. Hold on for a while and you will see the difference.
That depends on your situation. E.g. I sell it cheap because I guess there will be a price decrease in new projects most of the time, afterwards I will get it from cheaper. If you can evaluate a better choice, holding is not always a solution.
