Such thing as safe bet do not exist. In sports anything can happen and you can lose easily.
Thats why everybody should gamble only with money they can afford to lose.
Some people say that sports betting is more safe than other gambling games but this is infant not true. It maybe the fact that in sports betting you have something to think about and then take decisions but it is not 100% safe.
Gambling overall is not risk free. Every gambler must understand this before they start to gamble.
When I'm gambling I don't think of safety, I understand that everytime I do that I am risking money.
The risk of losing is always present as that is normal in gambling, however, we are hoping we can win that's why we are not afraid of taking risk.
We can call ourselves a real gambler if we are responsible at the same time, sports betting is fun and can give us better chance that games that has a house edge.
