Some people will tell you that what you use money for its achievement will tend to last more than the one that just comes on a platter of gold, we should know this for that reason, free things are sometime unpredictable and their value may not be as up to to the quality of what we get when we are actually using our own earned personal money for gambling, i don't know what's behind this, but that is how it has been for some time now.
This isn't completely true, there are people who had free money come their way and were able to use it well enough to get the very best off the money and today they have got investments they did made off the free money, so it's not all the cases that free money literally gets squandered without making something good off it, but then your idea does play out some times a d not always.
