I guess trading has to be done at the best time and with best skills . There is a need to know so much and speculate so much about the market before trading . I would not say that trading is bad , because many people get a lot of profit out of it . Holding is being on the safe side . Spending all the bitcoins trading other altcoins can be foolish as there must be something left as a backup .
Bitcoin is growing and hiking so holding is a very good way of getting profit by doing absolutely nothing.
