hodling is really really difficult specially of you do not have an influx of cash on a weekly/monthly basis. but of course there are always alternative altcoins which you can study and give focus to hodl like the ilcoin. take a look and you'll be amaze of its non stop development.
Well Holding is a part of trading. What I guess was meant here is actively using the money that you have as capital into trading and not holding any of it. That would be wrong since diversifying how you use your bought assets is an important thing in trading like a pro. You will make money from both and lose from both. Having a held off reserve not only will ease your mind that you have not lost a lot when trading but also act a emergency source of money in times of need.
Bitcoin users are more of hodlers at heart. But they do trade a certain part of their assets.
