I think it depends on each person, if they are really addicted to gambling, whatever the bitcoin price is... they must have prepared themselves beforehand. But it's good for us to be smarter in responding to this, gambling is like entertainment and we really have to know when it's time to gamble.
If you are smart enough to control yourself, the value of bitcoin is also your concerned, but likewise, if you are addicted to gambling there's no point that you'll be minding what't the current value, what inside you is how to deal with your gambling activities and nothing else, you'll spend your bitcoin whatever it takes.
It's always better to know how you deal with your budget, never to exceed and always find the entertaining part it will lessen the chance
of getting addicted since you are just treating everything as payment for your enjoyment.
