It can't be called gambling if you don't want to lose money.
If you don't want to lose then find a job but since you are working you are still exerting as much effort as you are gambling.
There is a balance in everything.
That's right. Anything in crypto currency has a risk thus you have to decide if you'll take it or ignore it anyway. The better thing to do if you don't want to lose is to find a job. Gambling and crypto currency is only for risk taker and opportunity seeker.
Ever heard the word "professional gambler "? Well there are people that are making decent living off gambling so if you're not fortunate to be one of them it doesn't mean it's not working and so you should ignore it. Even life is risk taking and everything we do involves some amount of risk so we should have this consciousness and we'd be able to have a good gambling life because there's no way to make sure you can't loose; you'll definitely loose sometimes.
