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.
