Well, if you don't count on "earning" as some here come up with, it will be more interesting to play again. But if these hundred bucks will determine your basic needs, then it is better to either reinvest them or just withdraw them and buy yourself some food (for example). I will play if I have a day off, and this money just came without having been obtained by hard work. Sometimes you need to know how to have a good time and pat luck on the ear.
