The easiest way to save money is to take a part of your salary saving in bank.
But it's not the best way. The best way is to invest something.
I would go for the safest way because I would never forgive myself if I would invest into something and in the end I would lose my money.
So I would just save my money in the bank where it is safe.
Everyone has its own risk level and it is fine if you don't have the guts to risk. But remember the old adage, no risk no gain. It is just fine to risk something for a greater gain as long as you studied everything before you invest. And putting it in a bank is not a safe option either. Banks can go bankrupt. And you lose to inflation rate over time.
