Gambling with bitcoins is similar to just gambling with real money. The problem is luck is too far most of the time. Its often easier to lose than to win. It's not really bad though because it's for leisure just don't put your heart too much on it.
But most people that do it don't see it as just a leisure or for it's entertainment value.
They are looking for a quick way to make some money or in this case some bitcoin.
It will lead to losses and possibly trying to buy more so to keep going to win from your losses.
Just stop because it is not really worth it in the long run.
So yeah, I would have to say it is wrong, only if you do not have it under control if you have a problem and running into your bank account to fund your gambling leisure outing.
