I generally play with the coins received from the free spins as I don't have to think about winning or losing with that money.
But when I play with my own money the money lost feels bad for a few hours but then again it's affordable to lose that kind of money.
It's good way to gamble with some sort of free coins but you don't get them in abundance and you need to spend your own funds into gambling.But if you have suffer loss from free funds then obviously it does not matter you a lot as it settled outside without any initial balance.But still losing any money gives you sadness whether free or paid.
