If you are not pressured by your live expenses and can afford to bank some bitcoin for a longer period of time.
There is no reason for you to not wait for price increase, you would be fool to sell your bitcoins before halving.
There are those who have just the amount they needed but still hold their bitcoins. It is the trust that soon it will rise and never fading courage to take the risk and hope for that moment that we can at least profit some in that rising moment.
