This is true, holding is not an easy thing for everyone who doesn't have any funds in trading.
You don't need to have funds to trade if you have no intention to trade but to hold.
But for me, it is important to manage your money and try to put an amount of money that is just for trading purposes only and do not sell your coins specially when you are getting nervous because of the price drop.
If you have no plans of selling it, you will have to hold it without any need to worry about trading it. Holding is easy if you have surpassed the bear market and still holds some assets.
