Worthwhile to buy silver?

Hi,
    I've recently become interested again in buying coins/precious metals and was wondering if it was worth it to buy silver at these high prices. If you guys think it is, which is a better deal, 1 ounce bars and rounds? or bulk silver coins? Also, what would be the best place to buy silver? Or if not, should I sell the silver I already own? Thanks.

who cares about profit now. hold it for the furture when you really need it if you can afford it now then you dont need the money that bad put it away in silver buy on the highs and lows theres no such thing as a perfect time to by if it gets to 4$ an oz will you be saying will it be smart or will it continue to fall? buy when you can
